(***) 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 2024-03-21 03:30 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 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour 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 sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. 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.

FS: Icom 910D 2m/70cm satellite transceiver
by JOHN GEIGER 24 Mar '24

24 Mar '24

I have for sale an Icom 910D 2m/70cm SSB/CW/FM transceiver that does dual receive so you can listen to both bands at once, as well as full duplex for the satellites so you can hear yourself on the satellite downlink. It also does normal and reverse tracking while in satellite mode making frequency control easier. Used it on some recent roves with good results. This is the Japanese model of the 910 so it does 50 watts on each band. Its frequencies are limited to 144-146mhz and 430-440mhz, so it does the satellite and weak signal portions of each band, but not the main repeater portions of the band. It may be modifiable to cover those frequencies. It has the optional Icom TCXO installed for frequency stability. That is a $100 option. It comes with the hand mic, power cord, manual written in Japanese, and original box. I am asking $550 shipped in the US. Pictures available via email. I can take paypal/check/MO/cash. 73 John AF5CC Sent using {0}

Time to start making plans to attend Hamvention 2024 from May 17-19, 2024 in Xenia, Ohio. This year's Hamvention theme is "Expanding our Community" and AMSAT plans to do exactly that by adding new members and recruiting more volunteers. Led by AMSAT Hamvention Team Leader, Phil Smith, W1EME, preparations are well under way. AMSAT, one of the larger Hamvention exhibitors, will again occupy 1,200 square feet of space at the north end of Building 1, also known as the Maxim building. This booth area has always been ideal for AMSAT because of the ample fresh air and easy access to the outdoor satellite ground station. Exhibits will feature members of the engineering team, CubeSatSim, Beginner's Corner, merchandise sales, Youth Initiative, software demonstrations and membership sign-ups. Also featured at this year's booth is information and sign-ups for the revitalized AMSAT Ambassador program. AMSAT will host its annual AMSAT Forum on Saturday from 1:10 to 2:10 in Room 2. Moderated by Phil Smith, W1EME, Robert Bankston KE4AL, AMSAT President, will highlight recent activities within AMSAT and discuss some of our challenges, accomplishments, projects, and any late breaking news. AMSAT Engineering Program: Jerry Buxton, N0JY, AMSAT Vice President for Engineering, will talk about the Current and upcoming satellite missions. AMSAT Education: Alan Johnston, KU2Y, AMSAT Vice President Education Relations will talk about the AMSAT CubeSat Simulator.

Join the AMSAT President's Club today and help Keep Amateur Radio in Space! https://www.amsat.org/join-the-amsat-presidents-club/ ------------------------------ AMSAT VP-Engineering Reviews GOLF Satellite Development Recently AMSAT News Service had the opportunity to interview Jerry Buxton, N0JY, AMSAT Vice President of Engineering, about the GOLF satellites that are currently in development. ANS: Jerry, the AMSAT engineering team is developing the GOLF (Greater Orbit, larger Footprint) satellites. What is the idea behind these satellites and the kind of functionality that will be added? JB: "Our original thought was for GOLF is to teach us how to go to Highly Elliptical Orbit (HEO.) Higher orbits have greater challenges than the satellites for LEO orbits we have built most recently. These are challenges like the higher radiation environment that the satellite must endure and controlling the satellite at higher altitudes. "We've had a significant additional requirement that has been added since GOLF was originally conceived. We must be able to deorbit the satellite on command. This is a pending FCC regulation. It is also likely that we will be required to move the satellite to avoid orbital debris in the future. To do this we have to be able to accurately know where the satellite is which requires a Global Navigation Satellite System (GNSS), which direction it is pointing which requires adding an Attitude Determination Control System (ADCS), and have a propulsion system to move it. This is not trivial. "Of course, we want to add more and more capabilities which require more power. "So, the purpose of the GOLF satellites is technology development, but they will have radios on board. Once they are up and we have proven the technology we will have another satellite that amateur radios operators can use." ANS: "What is the advantage of higher orbits?" JB: "Most of our current satellites are LEO, so we have about a 10 to 15-minute window to work the satellite. With higher orbits, the satellites will have a larger footprint (the signal will cover a larger area of the earth) and will be available or visible for longer periods of time. ANS: "Could you tell us a little more about how GOLF is being developed?" JB: "We will design and build the systems if we can, and we will acquire (buy) the functionality if need to. We are also using a stepped approach to capability development. We may fly the Attitude Determination Control System (ADCS) on the first satellite, add the propulsion system on the next satellite and so on. ANS: "Interesting! What else makes GOLF different from our previous satellites?" JB: "GOLF-TEE will have a new 3U space frame with deployable solar panels, which will flop open and lock into place. The solar cell system is an in-house design. It will have 14 cells on the satellite space frame and 28 on the deployable solar panels for a total of 42 cells, a significant increase in available power. "GOLF will have a radiation tolerant IHU (Internal Housekeeping Unit, or on-board computer.) It uses an automotive grade 32 bit ARM processor which has two processors. One is the primary. If one locks up the other takes over. The computer cores are in different areas of the chip and are at 90 degrees to each other, which lowers the likelihood of radiation affecting both processors. "We're adding microwave bands with a 10 GHz downlink experiment for increased data speed, that can also be used as a transponder downlink. This is a purchased radio. It has been a little bit of a challenge to fit the SDR into GOLF because it doesn't fit the normal layout. "GOLF will be much more complex than the FOX satellites. This complexity will increase the cost. This is because of the added capability the engineering team is developing like the additional solar panels as well as the selection and integration of purchased items like the ADCS or the 10 GHZ SDR radio." ANS: "Wow, the GOLF satellites will be a give us exciting new capabilities! When will they be launched?" JB: "The first is GOLF-TEE, which will be ready for launch in Q4 of 2025. GOLF-1 will be ready follow in Q4 of 2026. We should have some data and lessons learned from GOLF-TEE by then. "Here is a little more detail on the launch; GOLF-TEE and GOLF-1 have been approved by NASA as sound concepts and eligible for the ELaNa program. This program will pay for launch up to $300k of launch cost (covers everything up to a 3U satellite to LEO) and they will look for a launch that we can ride on. (We don't get to choose just when we launch.) A launch is not a guaranteed, but they always have found a ride for us." ANS: "Thank you, Jerry, for helping us understand these important new satellites!" [ANS thanks Jerry Buxton, N0JY, and Mark Blackwood, KI5AXK, for the above information.] ------------------------------ METEOR M2-4 Meteorology Satellite Readying for Operation Low earth orbit meteorology satellites are usually overlooked as an easy way to get newcomers involved in amateur satellites. They transmit with high power and gain antennas so they are easily received with a simple dipole antenna and a $30 RTL-SDR dongle that plug into a computer that most everyone owns. They are always on and transmit data that is actually fun and usable: very clear pictures of ones' own locale that is easily decoded with free software. From this first experience, it is a simple jump to tracking and copying the ARISS voice and APRS repeaters, and from there getting a Technician class license and inexpensive handheld. In addition to the NOAA low earth orbit polar meteorology satellites, the Russian METEOR M2-4 was recently added on February 29, 2024. It was launched into a 800km sun-synchronous orbit with a 98 degree inclination from the Vostochny Cosmodrome aboard a Soyuz 2 rocket. Having achieved orbit, it is currently undergoing testing and calibration. There is currently no information when setup will be completed, but it did take several months for NOAA to get the NOAA-21 satellite running. Once it is functioning it will begin transmitting its low-rate picture transmission (LRPT) imagery on 137.1 MHz and/or 137.9 MHz. The antennas are right-hand circular polarization but are easy received with a home-made three-element yagi or even a simple dipole. Complete information on suitable SDR receivers, and free receiving and decoding software can be found at rtl-sdr.com. A simple You Tube search on the topic will also provide you with enough demonstration videos to help get you started. More information at https://www.rtl-sdr.com/. [ANS thanks rtl-sdr.com for the above information.] ------------------------------ *Need New Satellite Antennas?Purchase M2 Antennas LEO-Packs from the AMSAT Store.When you purchase through AMSAT, a portion of the proceedsgoes towards Keeping Amateur Radio in Space!* *https://www.amsat.org/shop/* <https://www.amsat.org/shop/> ------------------------------ Satellite Tracking Rotator from Security Camera System No stranger to AMSAT publications, Gabe Emerson, KL1FI, publisher of saveitforparts.com is at it again. This month Gabe has posted a 24-minute video on how to use parts from an old security pan-tilt camera mount to build an az-el satellite rotator. The rotator motors are controlled by software based on the Australian School Amateur Radio Club Network (SARKNET) Rotator Mark I Arduino code. The software can be run on either an Arduino device or on a PC laptop. Gpredict is used in this example to track the satellites. Gabe uses the rotator to steer a small dish but it looks strong enough to handle a lightweight yagi such as an Arrow or Elk if suitably counterweighted. Even if you aren't interested in building this az-el rotator, Gabe's video is a fascinating look at how an inventive mind and resourceful scrounger can make something actually useful.

Weekly updates are completely adequate for most amateur satellites. Elements in the TLE bulletin files are updated daily. TLE bulletin files are updated to add or remove satellites as necessary Thursday evenings around 2300 UTC, or more frequently if new high interest satellites are launched. More information may be found at https://www.amsat.org/keplerian-elements-resources/ The following satellite has been added to this week's AMSAT-NA TLE Distribution: SONATE-2 - NORAD Cat ID 59112 Downlinks on 437.025 MHz, 145.825 MHz, 145.840 MHz and 145.880 MHz have been coordinated by the IARU. Thanks to Nico Janssen, PA0DLO, for the identification. The following satellite has been removed from this week's AMSAT-NA TLE distribution: BeliefSat-0 NORAD Cat ID 58695 End of mission. This mission was interesting as BeliefSat-0 is not a free flying satellite. Instead it is a "hosted payload" on a larger platform, in this case the spent upper stage of an Indian launch vehicle. The stage was modified such that it included solar panels and attitude control, so BeliefSat 0 and other payloads were designed to simply bolt on and plug in to a regulated power source. See https://www.isro.gov.in/POEM-3_Mission_achieves_Payload_objectives.html for details. While BeliefSat-0 and its host POEM-3 remain in orbit for now, it appears that BeliefSat-0 has been shut down as there have not been any successful observations of it in SatNogs for several weeks. POEM-3 will reenter within the next few weeks "leaving zero debris in space" according to the Indian Space Resource Organization.

As microcomputers emerged in the industry, Alan evolved into a computer technologist, working at Northstar Computers, Fantasy Records, and Dolby Laboratories. During the winter months of 1983 and 1984, he spent time in London as computer consultant to Hollywood film filmmaker, Stanley Kubrick. In retirement, he turned into a travel photographer, touring worldwide and documenting his experiences in still photos and video. First licensed in 1966, he was a consistent voice on RS-44 and an avid experimenter on IO-117 and other digital modes from CM87 in northern California. He earned AMSAT GridMaster Award #62 of which he was very proud, while grateful to the many rovers who worked hard to make that happen for him. We will miss hearing Alan on the birds!

Although it is not expected that the HamTV equipment will be activated for at least a few weeks, the British Amateur Television Club (BAT) has created a new wiki page which gives a lot of information on how to receive, decode and display the DATV signals from the ISS. See https://wiki.batc.org.uk/HAMTV_from_the_ISS; there is also a discussion channel available on the site.

[ANS thanks Abdul Alshahrani, HZ1DG for the above information.] + Tom Van den Bon, ZR6TG has been toying with this idea of adding a "Widget" to his Icom IC-9700. Playing with satellites requires various kinds of software that requires a fully fledged PC connected to the radio for tracking the satellite, controlling the rotator and automatically adjusting for Doppler effect. While all of that software works perfectly fine, Tom always wondered if there wasn't a simpler solution which is always available and ready at the radio. Tom says, "I know there are a few satellite "controllers" available that allow you to do something similar, but I felt that those are either too specific (i.e., only one radio and one rotator) or was lacking some features. My idea around the Satellite Tracking widget is to try and combine everything I need in a single small display."

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 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour 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 sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.

Many thanks for the information, David! I missed the previous activation of TEVEL-2 due to poor broadcast conditions and my bad habits. I am in fact a complete CW operator and I had difficulties, already finding a microphone (at my neighbor and nevertheless friend F1CZS), then with FM modulation. The problem seeming resolved, I will try again to-day when the bird will fly over Western Europe, around 11:55 UTC. I hope to meet there at least one of us. 73+++ David and all our friends on AMSAT-BB. Greetings and thanks to the Herzliya Science Center team, Jean-Pierre F5YG
