AMSAT NEWS SERVICE ANS-009 The AMSAT News Service bulletins are a free, weekly news and information service of AMSAT, The Radio Amateur Satellite Corporation. ANS publishes news related to Amateur Radio in Space including reports on the activities of a worldwide group of Amateur Radio operators who share an active interest in designing, building, launching and communicating through analog and digital Amateur Radio satellites. The news feed on http://www.amsat.org publishes news of Amateur Radio in Space as soon as our volunteers can post it. Please send any amateur satellite news or reports to: ans-editor [at] amsat.org You can sign up for free e-mail delivery of the AMSAT News Service Bulletins via the ANS List; to join this list see: https://mailman.amsat.org/postorius/lists/ans.amsat.org/ In this edition: * The ARRL Foundation Grants an Award for the ARISS *STAR* Keith Pugh Memoriam Project * EASAT-2 and Hades Satellites with FM Repeaters Scheduled for Launch on January 13th * Changes to AMSAT TLE Distribution for January 6, 2022 * ARISS News * Upcoming Satellite Operations * Hamfests, Conventions, Maker Faires, and Other Events * Satellite Shorts From All Over ANS-009 AMSAT News Service Weekly Bulletins To: All RADIO AMATEURS From: Radio Amateur Satellite Corporation 712 H Street NE, Suite 1653 Washington, DC 20002 DATE 2022 Jan 09 The ARRL Foundation Grants an Award for the ARISS *STAR* Keith Pugh Memoriam Project ARISS‐USA is known for engaging students in STEAM (science, technology, engineering, arts, and mathematics) subjects by arranging live question-and-answer sessions via amateur radio (ham radio) between K‐12 students and astronauts on the International Space Station (ISS). In the last two decades, over 1,400 contacts have connected more than one million youth using amateur radio, with millions more watching and learning. ARISS is constantly pursuing educational opportunities that inspire student interest and outcomes. ARISS-USA is pleased to announce that the ARRL Foundation awarded funding for the first year of a two-year project called the “ARISS *STAR* Keith Pugh Memoriam Project” with *STAR* being the acronym for Space Telerobotics using Amateur Radio. The ARRL Foundation very generously provided $47,533. The project honors the memory of highly-respected Keith Pugh, whose call sign was W5IU (Silent Key, May 2019). He was an expert supporter of ARISS for many years, a star ARISS Technical Mentor assisting schools with their ARISS contacts, finding educators who might be interested in learning about ARISS, and going to schools to lead youth in a variety of lessons about wireless radio technology. ARISS *STAR* (short for ARISS *STAR* Keith Pugh Memoriam Project), is a brand-new education program that will enable US junior high and high school education groups to remotely control robots through digital APRS (Automatic Packet Reporting System) commands using amateur radio. Year 1 focuses on systems development and initial validation of *ARISS* STAR, and Year 2 focuses on evaluation and final validation. Systems development and evaluation will be led by university staff and students who will undertake hands-on-wireless and telerobotics lesson development, learn about Amateur Radio, and support the development of the *STAR* engineering hardware and software. Next, youth teams will be selected to experiment and critique *STAR* telerobotics scenarios along closed courses and radio lessons. Some participating students will want to prepare for, and earn, their amateur radio licenses, using ham radio to learn and practice concepts in radio technology and radio communications. Overarching goals for *STAR* are to improve and sustain ARISS STEAM educational outcomes with youth. Robotics is gaining popularity among youth and adults alike. Telerobotics adds a wireless accent to robotic control. *STAR*, therefore, gives ARISS a new educational dimension to attract the attention of more education groups and their students and educators—outreach that promises to attract new audiences. The ARRL Foundation was established in 1973 by ARRL, The National Association for Amateur Radio ®, and advances the art, science and societal benefits of the Amateur Radio Service by awarding financial grants and scholarships to individuals and organizations in support of their charitable, educational and scientific efforts. ARISS-USA Executive Director Frank Bauer, KA3HDO, praised the ARRL Foundation, saying, “ARISS team member, Keith Pugh, W5IU, poured his energy into inspiring, engaging and educating youth in space and in amateur radio endeavors. What a better way to honor Keith than through the ARISS *STAR* initiative. We thank the ARRL Foundation for their vision to move this initiative forward. Maybe someday one of our ARISS *STAR* students will use their telerobotics skills to control scientific rovers on the Moon or Mars!” [ANS thanks ARISS for the above information] +=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+ The 2022 AMSAT President's Club coins have arrived!

As it has been noted in older posts, both satellites offer voice communications in FM and data retransmission in FSK or AFSK up to 2400 bps, such as AX.25 or APRS frames. They also transmit voice beacons in FM with the callsigns AM5SAT and AM6SAT, as well as CW, and, in the case of Hades, SSTV live images too. We thank you in advance for trying to receive their signals and of course for trying to use the repeater. EASAT-2 one will be automatically active 30 minutes after the launch although it would be a priority for us trying to have some telemetry frames first to check if all is working properly. I tell you a bit more about the satellites: EASAT-2 has been designed and built jointly by AMSAT-EA and students from the European University of Degrees in Aerospace Engineering in Aircraft and in Telecommunication Systems Engineering, with contributions from ICAI in the communications part, and it incorporates as an experimental load a basalt material from Lanzarote, similar to lunar basalts, provided by the CSIC research group on meteorites and planetary geosciences at the Institute of Geosciences, IGEO (CSIC-UCM) and that could be used as a construction material on the Moon. This project was promoted and has the collaboration of the ETSICCP (UPM). The UNESCO world geopark of Lanzarote and the Chinijo archipelago has been used for different investigations as an analogue of the Moon and Mars, also including the training of ESA astronauts. The selected basalt material meets the requirements to be used as a simulant of the existing basalt on the Moon. The purpose of the experiment is to determine its evolution in space based on periodic measurements of some of its properties. Although the experiment is limited and constitutes the first phase of this type of study, it represents an important milestone as it is the first of its kind to be introduced on such a small satellite. As for Hades, its payload consists of a miniature camera module that outputs the captured images as an audio signal in SSTV mode. The SSTV formats it uses are compatible with Robot36, Robot72, MP73 and MP115. The design of the cam module is based on the one used in the successful mission of the PSAT2 satellite, an amateur radio satellite of the United States Naval Academy and the Brno University of Technology. This camera has been operational since June 25, 2019: (http: // www.aprs.org/psat2.html). The camera chip is the Omnivision OV2640, which provides a resolution of up to 2M pixels and compressed JPEG output. The resolution is limited by the internal memory of the CPU (MCU) that controls the camera to 320x240 (typical) or 640x480 maximum. The MCU selected for the control is the STM32F446RET6, which has the smallest possible footprint with connection to a DCMI peripheral, necessary for the connection with the camera. Images can be stored in 2MB serial flash memory. The complete SSTV encoder has managed to be implemented on a 4 layer PCB with dimensions of only 38x38mm. The MCU can be fully controlled from ground stations. The firmware allows the sending of live camera images, images previously saved in flash memory, or images encoded in ROM. It also provides PSK telemetry and imaging advance scheduling with current status (event counters, temperature, voltage, light conditions, etc.) and a brief summary. The described module has been developed and manufactured in the Department of Radioelectronics of the Brno University of Technology in the Czech Republic. Both hardware and firmware designs with the source codes will be available on Github under the MIT license (https://github.com/alpov/SatCam). As noted, initially only the EASAT-2 repeater is active. Hades one will be activated by remote control a few days after launch. The frequencies coordinated with IARU for both satellites are as follows: EASAT-2 145.875 MHz uplink, Modes: FM voice (no subtone) and FSK 50 bps, AFSK, AX.25, APRS 1200/2400 bps 436.666 MHz downlink, Modes: FM voice, CW, FSK 50 bps, FM voice beacon with AM5SAT callsign HADES 145.925 MHz uplink, Modes: FM voice (no subtone) and FSK 50 bps, AFSK, AX.25, APRS 1200/2400 bps 436.888 MHz downlink, Modes: FM voice, CW FSK 50 bps, SSTV Robot 36, FM voice beacon with callsign AM6SAT The description of the transmissions can be found in the following document. https://www.amsat-ea.org/app/download/12530621/AMSAT+EA+-+EASAT-2+and+HADES… AMSAT-EA appreciates the receipt of telemetry, voice beacons and SSTV images.

Sunspots, X-class solar flares and CMEs (coronal mass ejections) are increasing in frequency and intensity on a daily basis. The peak of Solar Cycle 25 was not expected until late 2024 or early 2025 but it may be coming earlier and have a higher intensity than was predicted. One result of this increased activity is that the upper atmosphere and ionosphere of the earth becomes warmer and expands upwards. This means that spacecraft in low earth orbit experience more drag or resistance as a result of the increase in the number atoms they are having to displace as they travel around the globe. As a consequence, the spacecraft loose more kinetic energy and start to descend lower in orbital height, which, of course, makes the problem worse and a fiery end to the spacecraft is hastened. The actual effect is also dependant on the drag coefficient of the particular spacecraft…simply how much mass (the more the better) to how much surface area (the less the better). So in CubeSat terms, a 1U CubeSat, fairly full of stuff with a mass near the maximum of 1.3kg, will probably be better off than a half empty 3U CubeSat with deployable solar panels and other drag inducing protuberances. All TLEs (Two Line Elements) include a parameter called drag, it is usually a very small number preceeded by four or more zeros! Although this parameter is calculated by the system, it is not usually precise or even stable, so cannot be used to accurately predict deorbit dates when looking forward many weeks/months. It can give us a guide though! Alarm bells should ring when we only see two leading zeros. How does this effect our activities? Well for the FUNcube family, there are presently three active members! FUNcube-1, AO-73 was launched almost ten years ago in November 2013 into an elliptical polar orbit of approx 682×595 km. Presently those numbers are around 640×570 km so probably not too much to worry about. The drag number from the TLEs is, at the time of writing, 0.000074, a good number. The same applies to JY1SAT, JO-97. This was launched in December 2018 into a 573×590 km polar orbit. Presently those numbers are around 557×573 km and the current drag is listed as 0.000076. Unfortunately, however, the same cannot by said for Nayif-1, EO-88. This spacecraft was launched in February 2017 into a 496×507 km polar orbit. Currently the orbit parameters show a height of around 320 km with the drag at 0.00319. It is now well below the ISS and much lower than at launch. As mentioned, largely due to the random nature of the our star’s flux output on a day to day basis, it is not possible at this stage to accurately predict the likely deorbit date but it seems that it will certainly be before the end of this year. As the spacecraft continues to perform 100% nominally this is a great shame. Presently it is switching autonomously from high power telemetry when in daylight and with lower power telemetry and the transponder active when in darkness. The solar panels, battery and power system also continue to be reporting nominal numbers, essentially unchanged since the day of launch. It will therefore be a really sad moment when re-entry occurs but in the meantime everyone is encouraged to use the spacecraft whilst it remains available. To mark the event of EO-88/Nayif’s demise, AMSAT-UK is offering two awards. These will be individual framed certificates. Firstly, to the station who submits the last telemetry to the FUNcube Data Warehouse and also to who “guesses” or calculates the re-entry time and date most accurately. Submissions for this award must be made to EO88(a)amsat-uk.org before midnight (UTC) on July 4th 2023. So time is short to get your entries in. Good luck!

The satellite is a joint effort between AMSAT-EA, URE (the Spanish equivalent of ARRL), private companies, and universities. The URESAT-1 satellite, contained within the D-Orbit ION Orbital Transfer Vehicle (OTV), was not deployed directly from the Falcon-9 rocket. Instead, approximately one hour and twenty minutes after launch, the Falcon-9 released the OTV. URESAT-1 was deployed from the OTV at approximately 12:10 UTC on June 22, 2023. As of this writing, signals have not yet been received from the satellite. One of the primary objectives of URESAT-1 is to serve as an FM voice and FSK data repeater. Equipped with a Slow Scan Television (SSTV) camera, the satellite will transmit live images as well as stored images at regular intervals. It also features a chess game, enabling players on Earth to engage in a game against the satellite. Periodically, the satellite will transmit updates on the state of the game, including the chess board, the last movement made, and whether the next move belongs to the players or the satellite. The specified frequencies for communication with URESAT-1 are as follows: for uplink transmissions, 145.975 MHz or 145.925 MHz (auxiliary frequency) using FM voice without subtone, FSK 50 bps, AFSK, AX.25, APRS 1200/2400 bps. For downlink transmissions, the frequency is set at 436.888 MHz, and modes include FM voice, CW, FSK 50 bps telemetry, SSTV Robot 36, and a voice beacon with the callsign AO4URE. To provide further information regarding URESAT-1's transmissions, the AMSAT-EA organization has made available a comprehensive document that can be accessed at the following link: https://www.amsat-ea.org/app/download/13366685/AMSAT+EA+-+URESAT-1+Transmis… For those interested in decoding the telemetry, a Linux x86/ARM decoder is available for download at the following link: https://www.amsat-ea.org/app/download/13395017/URESAT-1_telemetry_decoder_L… A sample file containing the audio of a telemetry file can be found here: https://www.amsat-ea.org/app/download/13398144/URESAT-1_sample_FSK_telemetr… If URESAT-1 operates as intended, the project team plans to release a Linux program that will allow players to send their chess moves to the satellite, further enhancing the interactive experience.

Its baseline functions include telemetry, digital image downlink from an infrared camera, and digipeater with JT4G uplink/downlink. It will also provide chances for uploading and testing new waveforms and algorithms for radio communications and measurements in very long distance. Amateur radio orbit determination experiments, for example Very Long Baseline Interferometry (VLBI), are also possible with these links. Harbin Institute of Technology has previously successfully developed the first lunar amateur radio satellite, Longjiang-2 / DSLWP-B. (LO-94) As a subsequent mission, Lunar OSCAR II will continue offering various resources for communications relay and amateur radio research, and promoting the cooperation of amateur radio communities. The Lunar OSCAR II payload will be on board a lunar microsatellite with a volume of about 300x200x100 mm3 and a mass of about 14 kg and will utilize downlinks on UHF for telemetry and images using 250/500 baud GMSK with turbo codes and Digipeater using 4.375 baud $FSK with convolutional coding (JT4G). More information is available at https://by2hit.github.io/. The satellite is planned for a launch from Wenchang in 2024. A downlink on 437.750 MHz has been coordinated.

Just 10 years ago, a mere thousand or so operational satellites may have orbited our planet, but there will be tens or even hundreds of thousands a decade from now. Experts have been sounding alarm bells for years that Earth orbit is getting a bit too crowded. So how many satellites can we actually launch to space before it gets to be too much? Jonathan McDowell, an astrophysicist and astronomer at the Harvard-Smithsonian Center for Astrophysics warns the first signs that things are getting a little too tense are, in fact, already present. "It's going to be like an interstate highway, at rush hour in a snowstorm with everyone driving much too fast," he told Space.com when asked what the situation in orbit will be like if existing plans for satellite megaconstellations such as SpaceX's Starlink, OneWeb and Amazon Kuiper come to fruition. "Except that there are multiple interstate highways crossing each other with no stoplights." McDowell's British colleague Hugh Lewis is another frequently heard voice of caution. In a post published on Twitter on Jan. 13, Lewis stated that "the overall number of conjunctions predicted for 2022 was 134% higher than the number for 2020 and 58% higher than 2021, exceeding 4 million." That doesn't mean that on 4 million occasions objects in space came close to a collision — just that managing traffic in space is getting much more complicated than it has ever been in the past. Take SpaceX's Starlink as an example. According to information submitted to the U.S. Federal Communications Commission (FCC) in December last year, SpaceX's autonomous collision-avoidance system performed 26,037 orbital avoidance maneuvers with its Starlink satellites in the two-year period between Dec. 1, 2020 and Nov. 30, 2022. That means each Starlink satellite of the nearly 4,000 that have been launched to date performed, on average, 12 avoidance maneuvers during that time. But the size of SpaceX's current constellation is less than 10% of what the company plans to deploy. Within the next 10 years, the number of Starlink satellites in orbit may rise to 42,000. Add to that the up to 4,000 satellites that OneWeb wants to launch, another 3,200 of Amazon's Kuiper craft and 13,000 satellites of China's envisioned Guowang system, and it becomes obvious that things are set to get much more heated. According to the FCC document, SpaceX claims that each of its satellites has a sufficient amount of fuel on board to perform 350 collision-avoidance maneuvers over its expected five-year lifetime. But that number could be reached remarkably soon, according to Lewis' calculations. In short, less than five years from now, Starlink satellites may be running out of fuel in a shorter period of time than their designed lifetime because of the sheer number of avoidance maneuvers they will have to perform.

If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know. Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 0730 - 1930 UTC.

Re: ISS Launching Method of NanoRacks and CubeSat TLEs
by Nico Janssen 21 Jun '23

21 Jun '23

There are several ways small satellites can be deployed from the ISS: NRCSD (NanoRacks CubeSat Deployer), J-SSOD (JEM - Small Satellite Orbital Deployer), SSIKLOPS (Space Station Integrated Kinetic Launcher for Orbital Payload Systems), Bishop, and manually during a spacewalk (EVA). When using NRCSD, one or two pods, containing up to three Cubesats each, are placed on the deployment mechanism in the airlock of the JEM (Japanese Experiments Module, KIBO). The Japanese manipulator arm on the outside of the JEM, retrieves the deployment mechanism from the airlock and points the pods towards the aft of the ISS, at about 30 degrees below the horizon. At the required deployment time, the door of a pod is opened and the Cubesats are pushed out of the pod by a spring. Actually 11 deployments from the ISS are planned in the coming weeks, involving up to 29 satellites (details to be announced). You can witness these deployments live on a JAXA Youtube channel. 73, Nico PA0DLO On 21-06-2023 00:23, Brian Wilkins via AMSAT-BB wrote: > I recently became interested in learning about how the ISS launches > the cubesats that arrive on the NanoRacks. > > Where do they launch the cubesats from on the ISS? > > Also, when a cubesat leaves the ISS, and it likely has no propulsion > to prevent orbital decay, how long are the ISS TLEs relevant to the > CubeSats position?

About the TLE sets, from my experience, if you keep the TLE set of the ISS the moment of the deployment it can be useful from a 3-4 days to 1-3 weeks depending on several factors like the size of the cubesat or the height of ISS at the deployment time. By useful I mean that you will be able to spot the signal of the satellite in a waterfall but not exactly in the expected frequency, especially when the TLE set is too old. If you are interested and you want to perform an analysis on real data let me know and I'll point you to the data and some tools to analyze them. 73, fredy On 6/21/23 01:23, Brian Wilkins via AMSAT-BB wrote: > I recently became interested in learning about how the ISS launches the > cubesats that arrive on the NanoRacks. > > Where do they launch the cubesats from on the ISS? > > Also, when a cubesat leaves the ISS, and it likely has no propulsion to > prevent orbital decay, how long are the ISS TLEs relevant to the > CubeSats position?

ISS Launching Method of NanoRacks and CubeSat TLEs
by Brian Wilkins 20 Jun '23

20 Jun '23

I recently became interested in learning about how the ISS launches the cubesats that arrive on the NanoRacks. Where do they launch the cubesats from on the ISS? Also, when a cubesat leaves the ISS, and it likely has no propulsion to prevent orbital decay, how long are the ISS TLEs relevant to the CubeSats position? Days weeks? -- 73, ko4aqf(a)gmail.com

EO88’s re-entry competition from AMSAT-UK
by David G0MRF 20 Jun '23

20 Jun '23

After 6 years in space EO-88 / Nayif-1 is heading towards re-entry. To mark the event of it's demise, AMSAT-UK is offering two awards. These will be individual framed certificates. Firstly, to the station who submits the last telemetry to the FUNcube Data Warehouse and also to who “guesses” or calculates the re-entry time and date most accurately. Submissions for this award must be made to EO88(a)amsat-uk.org before midnight (UTC) on July 4th 2023. So time is short to get your entries in. This spacecraft, with it's mode U/V linear transponder, was launched in February 2017 into a 496x507 km polar orbit. Currently the orbit parameters show a height of around 320 km with the drag at 0.00319. It is now well below the ISS and much lower than at launch. It is not possible to accurately predict the likely deorbit date but it seems that it will certainly be before the end of this year. As the spacecraft continues to perform 100% nominally this is a great shame. Presently it is switching autonomously from high power telemetry when in daylight and with lower power telemetry and the transponder active when in darkness. The solar panels, battery and power system also continue to be reporting nominal numbers, essentially unchanged since the day of launch.It will therefore be a really sad moment when re-entry occurs but in the meantime everyone is encouraged to use the spacecraft whilst it remains available.https://funcube.org.uk/Good luckAMSAT-UK

First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 0730 - 1930 UTC. The most common times to find a crew member making casual periods are about one hour after waking and before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is active. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. **************************************************************************************************************************************** ARISS is very aware of the impact that COVID-19 is having on schools and the public in general.

The news feed on http://www.amsat.org publishes news of Amateur Radio in Space as soon as our volunteers can post it. Please send any amateur satellite news or reports to: ans-editor [at] amsat.org You can sign up for free e-mail delivery of the AMSAT News Service Bulletins via the ANS List; to join this list see: https://mailman.amsat.org/postorius/lists/ans.amsat.org/ ANS-169 AMSAT News Service Weekly Bulletins To: All RADIO AMATEURS From: Radio Amateur Satellite Corporation 712 H Street NE, Suite 1653 Washington, DC 20002 DATE 2023 June 18 Spain's URESAT-1 Collaborative Satellite Launches on SpaceX Transporter-8 The URESAT-1 satellite, also known as HADES-B according to its ITU designation, successfully launched into space as part of the SpaceX Transporter-8 mission from Vandenberg AFB on Monday, June 12. The satellite is a joint effort between AMSAT-EA, URE (the Spanish equivalent of ARRL), private companies, and universities. The URESAT-1 satellite, contained within the D-Orbit ION Orbital Transfer Vehicle (OTV), was not deployed directly from the Falcon-9 rocket. Instead, approximately one hour and twenty minutes after launch, the Falcon-9 released the OTV, which will orbit the Earth for several days before deploying URESAT-1, along with other satellites. One of the primary objectives of URESAT-1 is to serve as an FM voice and FSK data repeater. Equipped with a Slow Scan Television (SSTV) camera, the satellite will transmit live images as well as stored images at regular intervals. It also features a chess game, enabling players on Earth to engage in a game against the satellite. Periodically, the satellite will transmit updates on the state of the game, including the chess board, the last movement made, and whether the next move belongs to the players or the satellite.

Part of SpaceX's small satellite (smallsat) rideshare program, Transporter-8 carries dozens of small to pico-sized satellites and orbital test vehicles. This launch marks the 38th Falcon 9 rocket launch of 2023, showcasing the rocket's significance as the major workhorse in the space industry. As a rideshare launch, Transporter-8 doesn't have a primary mission but aims to lower costs for small spacecraft operators. The launch manifest for Transporter-8 includes an eclectic variety of missions. Among them is URESAT-1, a 1.5 P Pocketqube spacecraft from AMSAT-EA and the Spanish Amateur Radio Union (URE), equipped with an amateur radio payload that will attempt to play chess against opponents on Earth. Transporter-8's diverse manifest demonstrates the wide range of missions being pursued, from space manufacturing technology demonstration by Varda Space Industries to two cryptocurrency technology satellites (CRYPTO3 and MOXY-1) and a communications satellite for the Vatican (SpeiSat). This blend of missions highlights the growing importance and potential of small satellite deployments. With its rideshare model, SpaceX is enabling more affordable access to space for small spacecraft operators. By sharing the launch vehicle with multiple payloads, the costs are distributed among different customers, allowing them to realize their space ambitions at a fraction of the cost of a dedicated launch. The success of Transporter-8 adds to SpaceX's impressive track record, and if the company maintains its launch pace while incorporating successful Falcon Heavy rocket launches, it could be on track to achieve Elon Musk's ambitious target of 100 rocket launches by the end of 2023. SpaceX's dedication to advancing space exploration and commercial satellite deployments is evident in its consistent launch operations and commitment to driving innovation in the industry.

The challenge is to establish communication through the LEDSAT CubeSat digipeater, providing a chance to win a special prize: a QSL card issued by the ESA Education Office and the LEDSAT team. Running from June 26 to July 30, this challenge allows radio enthusiasts to engage with space technology and showcase their communication skills. LEDSAT, developed by students from Sapienza University in Rome's S5Lab research team with support from AMSAT Italia, is an educational 1U CubeSat that participated in the second edition of the Fly Your Satellite! program. Its primary objective is to demonstrate a LED-based payload for ground-based optical tracking. The successful launch of LEDSAT on Vega flight VV19 on August 17, 2021, marked a significant milestone for the project. To celebrate the launch, a competition was launched, encouraging participants from around the world to record the first signs of life from the spacecraft. To participate in the challenge, radio amateurs are invited to send a message to the ESA Education Office ESTEC Ground Station, with the callsign PI9ESA. The digipeater will be activated during specific time windows, with operators stationed at the ground station to receive incoming messages. Upon successful reception of a message, the sender's callsign and contact details will be documented on a personalized QSL card, acknowledging their accomplishment. The LEDSAT digipeater can store and retransmit digital messages sent to the satellite, acting as a transponder for long-distance communication. Messages can be retransmitted immediately or with an optional delay of up to two days. LEDSAT follows a Sun-Synchronous orbit, resulting in two communication windows each day – around midday and midnight – where contact can be established. Participants can predict passes precisely above the ESTEC ground station or their area of residence by using their favorite pass prediction software or obtaining the latest Two-Line Elements for LEDSAT from https://celestrak.org/NORAD/elements/gp.php?CATNR=49069. Due to LEDSAT's monitoring and housekeeping requirements and the potential high demand from operators, the digipeater activation time slots will follow a pattern of one day ON and one day OFF, with the switch-on/off always occurring at 00:00 UTC. This schedule will begin on Monday, June 26th at 00:00 UTC, and conclude on Sunday, July 30th at 24:00 UTC. While the challenge is supported by operators on a voluntary basis, efforts will be made to cover as many LEDSAT passes as possible, especially those occurring around local midday on weekdays. A detailed schedule of pass coverage will be published, so participants are advised to regularly check for updates. The LEDSAT digipeater uplink frequency is 435.310 MHz, the downlink frequency is 435.190 MHz, and the modulation type is GMSK using a CSP + Golay + ASM (AX100 Mode 5) protocol at 1200 baud. The LEDSAT team has prepared a software package and a user manual for connecting to the digipeater, available for download on the LEDSAT website at https://www.s5lab.space/index.php/ledsat-digipeater/. It is important to note that transmitting to the satellite is prohibited for those who are not licensed radio amateurs. However, non-licensed individuals can still participate in the challenge by listening to the messages transmitted by the ESTEC ground station. If they provide evidence of successful reception, including the date and time, they may also receive a customized QSL card. Participants are encouraged to mark their calendars, prepare their messages, and not miss the chance to connect and communicate with the LEDSAT spacecraft to receive their QSL card. Let's come together and make this event a memorable celebration of our shared passion for space exploration and amateur radio communication.

Moon Day, July 22nd, Frontiers of Flight Museum -- Volunteers needed.
by tjschuessler＠verizon.net 17 Jun '23

17 Jun '23

The Frontiers of Flight museum in Dallas, Texas, Love Field, is again this July 22, having it' annual "Moon Day" event on Saturday July 22nd. This is a large Space theamed STEM event held at the Museum for 15 years now. Regularly attracting 1200-1500 people, from young children and families, to the young at heart. Many organizations have tables, displays demos and presentations. I have been representing Amateur Radio Satellites, and AMSAT for many years now. We show off the types of satelites that AMSAT has/is developing, explain orbits/footprints, show off the cubesat simulator, and do live satellite pass demos. We do present how Amateur Radio makes space accessible to the average person. We are located right next to the Dallas Amateur Radio Club, who also is a regular participant. There are a couple of other satellite enthusiasts who usually assist in manning the inside display table, but there is always the need for additional folks to work the table, explain concepts, and do satellite communications demos out on the parking lot. If you live in the DFW area, are planning o be visiting, or just want to come and have a fun time explaining Amateur Radio in Space to a broader audience than just licensed hams, (We though routinely bump into lots of folks who have a license, but haven't gotten going with the hobby), please get in contact with me off list and I will give more details. Date; July 22nd, 2023 Time; 8AM setup. 10A-4P doors open Place; Frontiers of Flight Museum, Dallas Love Field, Dallas, TX Web. https://www.flightmuseum.com/ P.S. If someone has a general public and space enthusiasts presentation on how satellites get to orbit, and stay there, if you can get with me ASAP, I may be able to get us a presentation slot. Just thought of this idea. 73, Tom Schuessler, N5HYP N5hyp(a)arrl.net

Ambassador Notes
by Clint Bradford 16 Jun '23

16 Jun '23

Several “Getting Started … “ presentations in the works! Fine clubs in these cities are firming up their post-Field Day calendars for club presentations ... Daytona Beach McKinney, TX Holiday City, NY Sevierville, TN Dover, Delaware Lake Havasu City, AZ Thames Valley, SE England Think a 75-minute presentation on “working the easy satellites” would be appropriate for your club or event? Let me know! I have NEVER given the exact same show twice: EACH of the 150+ presentations so far has been customized/tailored to my audiences. An email message received after a recent presentation … "I really enjoyed Clint’s presentation last night. The fact that he had taken the time to research and know something about his audience and welcomed interaction made it very informative and enjoyable. This was a refreshing change from many canned YouTube presentations I’ve tried to watch, which were poorly done, fuzzy video or muddy audio, or a badly prepared presenter stumbling his way through, with any valuable info lost along the way. Thanks for hooking this one up.” Clint Bradford K6LCS AMSAT Ambassador ARRL instructor, Legacy Circle member, Affiliated Club Coordinator work-sat.com <http://work-sat.com/> <http://work-sat.com/> 909-999-SATS (7287)

If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know. Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time. All dates and times listed follow International Standard ISO 8601 date and time format YYYY-MM-DD HH:MM:SS The complete schedule page has been updated as of 2023-06-13 18:30 UTC. (***) Here you will find a listing of all scheduled school contacts, and questions, other ISS related websites, IRLP and Echolink websites, and instructions for any contact that may be streamed live. https://www.amsat.org/amsat/ariss/news/arissnews.rtf https://www.amsat.org/amsat/ariss/news/arissnews.txt The successful school list has been updated as of 2023-06-12 20:30 UTC. https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 0730 - 1930 UTC. The most common times to find a crew member making casual periods are about one hour after waking and before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is active. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. **************************************************************************************************************************************** ARISS is very aware of the impact that COVID-19 is having on schools and the public in general. As such, we may have last minute cancellations or postponements of school contacts. As always, I will try to provide everyone with near-real-time updates.

Right in time when I was giving a live demo to a 10 year old kid 73 Nitin [VU3TYG] On Monday, 12 June, 2023 at 04:32:53 pm IST, David G0MRF via AMSAT-BB <amsat-bb(a)amsat.org> wrote: Nice to see Greencube / IO-117 back to digipeating from 06.00 this morning.

It was off for a couple of days around the 13th of May but it was 'reset'? and back to normal by the 15th. It's a little unclear who can uplink commands to GreenCube / IO-117. The owners are S5Labs, but their primary mission was concluded last fall.AMSAT Italy are also listed as partners, but I'm not sure how far that involvement goes. I wondered if anyone on the list is decoding telemetry. The battery voltage is normally 8.2V. A quick look at the tlm may reveal if there is an issue, or if the satellite has been commanded to telemetry only. 73 David G0MRF -----Original Message----- From: David Spoelstra via AMSAT-BB <amsat-bb(a)amsat.org> I got on Greencube for the first time on Wednesday and made a bunch of contacts. On Friday Greencube was only sending telemetry and is still in telemetry only mode. Is it normal for the digipeater to be off for several days at a time? Is there a schedule? 73,-David, N9KT ----------------------------------------------------------- Sent via AMSAT-BB(a)amsat.org.

(***) https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 0730 - 1930 UTC. The most common times to find a crew member making casual periods are about one hour after waking and before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is active. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. **************************************************************************************************************************************** ARISS is very aware of the impact that COVID-19 is having on schools and the public in general. As such, we may have last minute cancellations or postponements of school contacts. As always, I will try to provide everyone with near-real-time updates.

Yes, it has been active but takes some power and gain to work. I was able to be digipeated using 50 W and a 4-element yagi. -Stephen N8URE

URESAT-1 launch today from Vanderberg (SpaceX TR-8)
by Félix Páez 12 Jun '23

12 Jun '23

Dear friends, Today it is planned the launch of our satellite URESAT-1 (HADES-B ITU designation). The satellite has been a joint effort by AMSAT-EA, URE (the equivalent in Spain for ARRL), private companies and Universities. It flies on the SpaceX Transporter-8 mission to be launched today at 21.19 UTC from Vandenberg AFB. URESAT-1 will not be deployed directly from the Falcon-9 as it is contained in the D-Orbit ION Orbital Transfer Vehicle (OTV). The Falcon-9 will deploy the OTV 1h and 20 minutes after launch and this OTV will be orbiting the Earth for several days before deploying URESAT-1 along with other satellites (initially for 1 week). We will try to provide TLEs for it as soon as we have them. The satellite's main mission is to act as an FM voice and FSK data repeater (like AX.25). It has a SSTV cam that alternates between a live image (without pointing) and stored images. It also has a chess game so players on Earth can play against it. Periodically the satellite transmits the state of the game, including the chess board, as well as the last movement made and who's turn (players or satellite). Work frequencies are as follows: Uplink: 145.975 MHz/145.925 MHz (aux), Modes: FM voice without subtone, FSK 50 bps, AFSK, AX.25, APRS 1200 / 2400 bps Downlink: 436.888 MHz, Modes: FM voice, CW, FSK 50 bps telemetry, SSTV Robot 36, voice beacon with callsign AO4URE. Be aware that the FM transponder needs to be activated first time by telecommand. Here you have the document describing the transmissions: https://www.amsat-ea.org/app/download/13366685/AMSAT+EA+-+URESAT-1+Transmis… Here you have an sample file with the audio of a telemetry file (chess board): https://www.amsat-ea.org/app/download/13398144/URESAT-1_sample_FSK_telemetr… Here it is the Linux x86 / ARM decoder for telemetry: https://www.amsat-ea.org/app/download/13395017/URESAT-1_telemetry_decoder_L… If the satellite works fine we will deliver a program for Linux so players can send the chess moves to the satellite! Fingers crossed! 73, Felix EA4GQS - AMSAT EA President
