ISS Deployment (JAXA) J-SSOD#22 - 2022-08-12 12:40 UTC

Satellites & Observations Launches
1

Greetings!

If the schedule holds, the time has arrived for another deployment from the ISS ‘Kibo’ module.

Would it be possible to assign temporary ID #'s for the three satellites involved?

Can anyone help with the downlink mode for ‘Futaba’? Also please speak up if I’ve gotten any of the frequencies wrong.

TUMnanoSAT / 436.680 / 9k6 GMSK AX25

Futaba / 437.375 / 1k2 ???

HSU-SAT1 / 437.280 / 1k2 custom framing (http://uz7.ho.ua/hsusat.zip + gr-satellites) / 9k6 custom framing (http://uz7.ho.ua/hsusat9600.zip [NOT yet in gr-satellites])

Per a tweet from JA0CAW: The deployment event for those satellites by J-SSOD#22 will be broadcast via JAXA Channel.
August 12, 2022 （Friday）
18:25-18:55 (JST)

Thanks!

I can see on the following page, that these are all on the list of “List of Satellite projects for which frequencies have been coordinated” with IARU (afaict, all the names match).

The satellites are in DB and Network:

Satellite Identifier Name Temporary NORAD ID
VNRS-0413-3415-7769-6012 HSU-SAT1 99349
TXQM-7768-3090-1795-9214 FUTABA 99350
EUEU-0112-5297-2105-4789 TUMNANOSAT 99351

For now we follow ISS TLE set.

I’ve just scheduled ~500 obs for the three satellites for the first 48h. Given that we use TLE set of ISS please if you schedule leave some spots for people that want to track ISS itself.

Welcome Tetsu san, nice to see you here.

More and more observations with all the satellites alive, and several frames from TUMnanoSAT. Here are the good observations:

We have 3 TLE sets for the satellites from space-track.org. Still they are on “To Be Assigned” status, so it is too early for any identification. The TLE sets:

0 TBA - TO BE ASSIGNED
1 53462U 98067UB  22224.81257517  .00068066  00000-0  11505-2 0  9998
2 53462  51.6429  56.0717 0008373 137.0890 341.1382 15.50928298    72
0 TBA - TO BE ASSIGNED
1 53463U 98067UC  22224.81302378  .00005452  00000-0  10000-3 0  9995
2 53463  51.6460  56.0737 0009027 139.0341 341.7585 15.50966492    79
0 TBA - TO BE ASSIGNED
1 53464U 98067UD  22224.81290759  .00119512  00000-0  19942-2 0  9991
2 53464  51.6435  56.0671 0008357 140.6627 339.5439 15.51026136    75

The objects are pretty close so all the three TLE sets can be used for tracking the satellites. So, for now we have:

Name Temporary NORAD ID Followed NORAD ID Other Possible NORAD IDs Status Update
HSU-SAT1 99349 53462 53463, 53464 Received Random Choice of the Followed NORAD ID
FUTABA 99350 53463 53462, 53464 Received Random Choice of the Followed NORAD ID
TUMNANOSAT 99351 53464 53462, 53463 Received Random Choice of the Followed NORAD ID
10

Still only CW from HSU-Sat1, but the good news is that on the 2020utc pass (13-Aug-2022), it tracked PERFECTLY with Object # 53462. Of course, they are still very close together, but just wanted to pass along that observation.

Now that the space-track.org TLE have been assigned, we have with some ikhnos analysis:

Name Temporary NORAD ID Followed NORAD ID Other Possible NORAD IDs Status Update
HSU-SAT1 99349 53462 53463(unlikely) Received Rejected 53464
FUTABA 99350 53463 53462(unlikely), 53464 Received The signal drifts a lot making identification difficult, so we will need more separation
TUMNANOSAT 99351 53464 53462(unlikely), 53463 Last Received in observation at 2022-08-12 13:11 Random Choice of the Followed NORAD ID

Some extra confirmation that HSU-SAT1 is following 53462
