Upcoming ARISS Contact Schedule as of 2023-01-06 17:00 UTC Quick list of scheduled contacts and events: Escola Secundária de Lagoa, Lagoa, Azores, telebridge via IK1SLD (***) The ISS callsign is presently scheduled to be OR4ISS (***) The downlink frequency is presently scheduled to be 145.800 MHz The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The scheduled crewmember is Josh Cassada KI5CRH (***) Contact is go for: Wed 2023-01-18 17:32:02 UTC 41 deg (***) The crossband repeater continues to be active. 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. 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. Watch for future COVID-19 related announcements at https://www.ariss.org/ The following schools have now been postponed or cancelled due to COVID-19: Postponed: No new schools Cancelled: No new schools **************************************************************************************************************************************** Note, all times are approximate.

Hello everyone: According to my latest simulation, FalconSat will reenter on Jan 22, 2023 at 16:6:6 EST. Just wanted to let people know. It's not super accurate because things speed up unpredictably during the end, but it's a fairly good estimation I think. 73! VE3SVF

You are going to run into serious trouble if you live near high power transmitters, especially FM. The front end of the RTL-SDR has poor large signal handling capabilities.

AMSAT NEWS SERVICE ANS-008 In this edition: * Story of SuryaSat-1 (SS-1) Nano Satellite * VUCC Satellite Standings as of January 1, 2023 * ARISS News * Upcoming Satellite Operations * Hamfests, Conventions, Maker Faires, and Other Events * Satellite Shorts From All Over 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/ ANS-002 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 Jan 08 Story of SuryaSat-1 (SS-1) Nano Satellite This afternoon 6 January 2023, at 07:50 UTC, there will be the culmination of the long journey of Surya Satellite (SS-1) Nano Satellite project that started in 2016 after a presentation of amateur radio activities by ORARI (the Indonesian Radio Amateurs Organization) to students of University of Surya. In early 2015 ORARI made a presentation to University of Surya Robotic Club, and one of the amateur radio activities that got their interest was high-altitude ballooning due to the telemetry aspect, such as sending temperature, altitude, voltage, as it relates to their robotic interest. I showed them a couple pictures of my past activity in ARHAB as the faculty advisor of amateur radio society at Texas Tech University in early 2000. This started the high-altitude balloon planning, including designing the balloon payload (APRS utilizing OpenTracker mini board). Late 2015, with the successful launch and activation of LAPAN-A2/ORARI (which becomes IO-86) satellite, the students grew interest of building a satellite as it is only a couple of kilometers higher they said. So in 2016 the ORARI team visit them and shared the experience in designing a satellite, as I myself was part of the ORARI team that involved in the design of the amateur payload in the LAPAN-A2/ORARI. As this would be their first effort in building a satellite from scratch, they said we will start with APRS then next satellite would be a voice repeater satellite. They submitted the design in a competition by UNOOSA and won. The student got more excited after seeing the POC (proof of concept) worked and they continue with building the prototype, conducted various tests with LAPAN (the aeronautical and space organization) and complying with the necessary paperwork/approvals. But the road wasn’t easy as they got funding problem (at one time they were selling T-Shirt to raise funding), change in faculty advisor and university leadership and their own graduation and transition into the professional world (some of them got employed in commercial satellite companies). Finally they got back in the last 2 years to finalize the payload, had the payload verification with ORARI team and shipped the payload to Japan (JAXA), integrated with other payload and shipped to the US, then lifted up on Space-X CRS-26 rocket to ISS last November and now today is the deployment date from the Kibo Module of ISS. Apologize for the long posting but I got really excited today as the deployment of SS-1 Nano Satellite is coming up shortly. Update: SS-1 has been deployed at 08:03 UTC on 6 January 2023 please monitor APRS beacon at 145.825 MHz [ANS thanks Yono Adisoemarta, YD0NXX / N5SNN, ORARI HQ, Head of Satellite Division, for the above information] +=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+ The 2023 AMSAT President's Club coins are here now!

Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated 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/ At the request of CAMSAT and the XW-4 (CAS-10) team, AMSAT has designated the satellite as Hope-OSCAR 119 (HO-119) as of January 1, 2023. For details, see Drew Glasbrenner, KO4MA and OSCAR Number Administrator's announcement entitled "OSCAR number assigned for CAS-10" in AMSAT News Service Bulletin ANS-001 (dated January 1, 2023). Therefore, the following satellite has been renamed in this week's AMSAT-NA TLE distribution as follows: HO-119 NORAD Cat ID 54816. (Formally CAS-10). The following satellite has decayed from orbit and has been removed from this week's AMSAT-NA TLE distribution as follows: TW-1A NORAD Cat ID 40928. (decayed from orbit on 12/29/22 per Space-Track). Finally, AMSAT is pleased to announce the new daily two line element bulletin available at https://www.amsat.org/tle/current/daily-bulletin.txt. Members of the Sci-Tech Radio Society (STARS) have worked with AMSAT Information Technology to automate this process. Seventeen year old STARS member Ryan "RJ" Fitzgerald, N1BGA, enjoyed exercising skills he learned in his high school computer science class. "It was cool to do something for the real world beyond just homework assignments, plus it forced me to learn stuff not covered in class" said Fitzgerald. STARS is part of New England Sci-Tech - a non-profit STEM education center and makerspace dedicated to project-based, hands-on learning for youth and families across the New England community with a strong Amateur Radio focus. Visit www.nescitech.org for details. Thanks to Joe Fitzgerald, KM1P, for this update on this new innovative approach to AMSAT TLE distribution. [ANS thanks Ray Hoad, WA5QGD, AMSAT Orbital Elements Manager, for the above information] --------------------------------------------------------------------- ARISS News Amateurs and others around the world may listen in on contacts between amateurs operating in schools and allowing students to interact with astronauts and cosmonauts aboard the International Space Station. The downlink frequency on which to listen is 145.800 MHz worldwide. No upcoming contacts currently scheduled Special thanks to our ARISS telebridge ground stations. Approximately 38% of the ARISS school contacts are handled by the ARISS telebridge stations. Thanks to following stations: AB1OC, IK1SLD, K6DUE, NA7V, ON4ISS, VK4ISS, VK4KHZ, VK5ZAI, VK6MJ, and ZS6JON. The crossband repeater continues to be active. 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. 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.

This launch carried 114 satellites to orbit. The article says "The Transporter 6 launch also placed into orbit... an amateur radio CubeSat from the Czech Republic." I assume that is a reference to BDSAT-2, which is supposed to carry a AX.25 GFSK G3RUH 9600 baud digipeater with downlink at 436.025, according to http://www.amsatuk.me.uk/iaru/finished_detail.php?serialnum=866 This is confirmed by https://www.bdsat.cz/ That website shows "VHF Downlink frequency: 145.850 MHz," but the IARU says the VHF frequency is an uplink. (Thanks to Mark Johns, K0JM, SpaceFlight Now, and the IARU) + The TJREVERB are seeking a couple of stations skilled in communicating with satellites using APRS. The Thomas Jefferson High School for Science and Technology's TJREVERB satellite was deployed from the ISS on Dec 29th, and the team is still trying to successfully make contact with it. Please contact Curt Laumann, K7ZOO, if you're interested in assisting. His email address can be found on QRZ.com + Congratulations to Hector Martinez, W5CBF, who finished his Satellite Worked All Zones (WAZ) award through QSOs using IO-117's MEO digipeater. Only about 16 CQ zones are workable on LEO satellites from his QTH in Louisiana, so the MEO digipeater was able to fill in the rest. His award is the 42nd Satellite WAZ issued. Satellite WAZ requires confirmed QSOs with 25 of 40 CQ zones and is sponsored by CQ Magazine. Confirmations through LoTW are accepted. + Want to try something different? FO-118 carries a linear transponder with a 70cm downlink and a 15 meter uplink. The 15 meter uplink is very sensitive. This week's editor made a couple of QSOs using 5 watts from his FT-817ND to an AlexLoop Walkham Portable Magnetic Loop and was able to access the transponder with strong signals through the pass. + UVSQ-SAT will mark 2 years in space on January 24, 2023. In celebration of this milestone, the FM transponder will be activated. The uplink is 145.905 MHz and the downlink is 437.020 MHz. No PL tone is required.

SS-1 Satellite - First 24hr Report
by P. Suryono Adisoemarta 07 Jan '23

07 Jan '23

Quick SS-1 (Surya Satellite 1) Report after a meeting with the SS-1 Satellite team an hour ago:- SS-1 was deployed at 08.03 UTC on Jan 6, 2023- Right on schedule, 30 minutes after deployment first packet was heard. This packet was digipeated via ISS as it is still close-by- From the telemetry bits, both VHF and UHF antennas were properly released- Battery voltage was observed at 3.83 volt- At around 13.00 UTC SS-1 went quiet, the team concluded it went into "hibernation mode" due to low voltage- This morning at around 00.30 UTC one observer in Bali received a direct (not digipeated) packet, so it came out of hibernation mode with high voltage as the radio power is high- Consecutive packets were received direct by various APRS satgates- At around 07.00 UTC telemetry shows a critical low battery voltage and SS-1 went into hibernation again- As the SS-1 team concluded that the satellite is working as designed, 2 hours ago when SS-1 pass above Jakarta, the team uplink commands to reduce the beacon rate, to raise the battery voltage, and gather more data points on the power budget model. 73 de Yono - YD0NXXORARI HQ - Head of Satellite Division

There is also a new TLE set for SS-1, not very accurate but it should be better than following ISS TLE: SS-1 1 99369U 23006.23627038 .00000000 00000-0 25952-3 0 07 2 99369 51.6447 51.3209 0004899 231.6381 242.1444 15.51123116 06 Source: https://community.libre.space/t/iss-deployment-jaxa-j-ssod-24-2023-01-06-07… 73, fredy On 1/7/23 10:31, Jean Marc Momple via AMSAT-BB wrote: > Thanks Fredy for having confirmed. > > 73 > > Jean Marc (3B8DU) > >> On Jan 7, 2023, at 11:37 AM, Alfredos (fredy) Damkalis via AMSAT-BB <amsat-bb(a)amsat.org> wrote: >> >> Yes this is the callsign of SS-1. >> >> By the way SS-1 is active on both UHF and VHF, but difficult to catch it on VHF as it is still close to ISS and its APRS repeater.
