AO-95 QRT

After a lingering illness of the battery, AO-95 passed away peacefully on December 23rd. While a miraculous return is always possible, it is not expected.

AO-95, known prior to launch as Fox-1Cliff to commemorate amateur satellite pioneer Cliff Buttschardt, K7RR, who became a silent key in 2007, launched on December 3, 2018 on a SpaceX Falcon 9 from Vandenburg Air Force Base. Shortly after deployment, the AMSAT Engineering team received nominal telemetry data from the satellite, but upon the first attempts at commanding, it was discovered that the receiver had failed for unknown reasons. Still, the satellite provided an easy to receive beacon and telemetry data for over four years before the NiCd batteries failed.

New Satellite Distance Records

A number of new distance records via satellite have been claimed over the past couple of months. First is the massively popular new MEO satellite IO-117. Burt DeMarcq, FG8OJ, worked Shigenori Nasu, JH8FIH, on November 25, 2022 at 08:22 UTC. The distance between FG8OJ in FK96hg63 in Guadeloupe and JH8FIH in QN14qi16 in Japan is 12,823 km.

Note that for future claims of IO-117, only live QSOs may be counted and not those completed over multiple orbits using the satellite’s delayed messaging capabilities.

A new distance record was also claimed via the QO-100 geostationary satellite. PT9AL in GG27os in Brazil worked XW4KV in Laos OK27jj on December 10, 2022 at 14:41 UTC. The distance between the two stations is 17,834 km, eclipsing the previous record held by PR8KW and YC5YC of 17,378 km.

Finally, FO-118, launched in December is a LEO satellite carrying three transponders. Familiar faces for the AMSAT Satellite Distance Records have claimed the initial record on all three transponders – the V/u FM transponder, the V/u linear transponder, and the H/u linear transponder (15 meter uplink). F4DXV and VE1CWJ completed transatlantic QSOs on all three transponders. On January 6, 2023 at 04:15 UTC, they completed a QSO via the V/u FM transponder and then switched over to the V/u linear transponder to complete a QSO there one minute later. VE1CWJ was in FN85do83sg and F4DXV was in JN04js20pr. They completed the sweep of all three transponders on January 30, 2023, when they completed a QSO via the H/u linear transponder at 17:16 UTC. VE1CWJ was in the same location while F4DXV was in JN04it22nt for this QSO, for a distance of 4,908 km.

Anyone who wants to claim a distance record via an amateur satellite should check the current list at https://www.amsat.org/satellite-distance-records/ and email n8hm at arrl.net if they complete a new record distance. Audio and/or video of the QSO is encouraged but not required.

Changes to AMSAT-NA TLE Distribution for February 2, 2023

Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. 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/

AMSAT IT, in conjunction with the New England Sci-Tech STEM Education Center assembled a tiger team of software experts from the Olin College of Engineering, Boston Latin School and the Wilson Middle School to investigate the recent disappearance of AO-7 from www.amsat.org/tle/current/dailytle.txt and the legacy naasbare.txt files.

The team determined that AMSAT’s processing is not robust in the face of minor format differences in the source data received from the USSF’s 18th Space Defense Squadron. Specifically, the TLE data provided does not always include the leading zero in AO-7’s object number “07530”. The official report from the team’s leader : “My grandma would say that AMSAT’s software is just a little too persnickety”. A member of the tiger team agreed to adjust the update script to account for the vagaries of the 18th SDS data. A production quality fix is expected by March 1st, meanwhile manual monitoring and updates will keep AO-7 in the files.

There were no changes to the February 2, 2023 distribution.

Starting about 15 minutes before AOS, watch for Livestream at https://bit.ly/3X5EI4s

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://bit.ly/3vKe2LF 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.

Satellite Shorts From All Over

+ The FO-99 operation schedule for February is available at https://www.jamsat.or.jp/?p=2079 (Thanks to JAMSAT for this information)

+ A volunteer is being sought to take over the Gridmaster Heat Map on Twitter. Paul Overn, KE0PBR, has announced his intent to “retire” from the project that he has moderated there for the past three years. Paul has assisted many grid chasers by relaying information about rovers, and keeping tabs of which grids are in greatest need. Unless someone steps forward, Gridmaster Heat Map will disappear next month. Thanks to Paul for your valuable contribution to satellite operations! (ANS thanks Paul Overn,
KE0PBR, for this information)

+ A while ago, perhaps almost two years ago, I modified the LVBTracker firmware in my Fox Delta ST2-USB so that it would allow for more calibration points than just the min and max for azimuth. I had added a remote-control option to an old Yaesu G-450XL, but the output voltage was very non-linear, which led to terrible aiming of the antennas. With the mods I made to the firmware it now allows me to calibrate the controller at 0, 90, 180, 270, and 360 degrees and aiming is now rather accurate. I wrote about it here:

Fox Delta ST2 / LVBTracker Calibration Mods

If you feel this could be useful for you, the source code for the project can be found on GitHub:

https://github.com/TheHamLab/LVBTracker.KR1ST

(Thanks KR1ST for this information)

+ SuitSat-1 (AMSAT-OSCAR 54) deployed from the ISS 17 years ago February 3rd. It played voice messages in languages recorded by the ARISS partners and students from around the globe. It also sent telemetry data. It was lost 15 days later. SuitSat came back to life in a 2021 short horror film! If you’d like to watch the Sci-Fi Horror short film “Decommissioned” based on the ARISS SuitSat, it can be found on YouTube at https://www.youtube.com/watch?v=TNtpdvfbTjA (Thanks ARISS for this information)
