GNU Radio w/ gr-satellites support for ASRTU-1 doing a fine job via my 2.5-turn helical omni antenna for these telemetry downlinks. Appeared to be a camera image downlink streaming on-command from uplink via N6RFM’s station this morning!
So great that you can receive, decode, & contribute frames from a satellite like this without even needing a rotator or expensive antennas.
Updated TLE for SamSat-Ionosphere:

Ionosfera-M satellites should transmit beacons at 150 and 400 MHz, then also a data downlink in the 137 MHz band, and possibly in the 1.7 GHz band
New TLE set for Kosar based on the latest observations, not fully accurate as we need more good observations for fitting it:

EDIT:
I’ve also updated the transmitter to 38k4 as this is how they show up in observations (which by the way is similar to another Iranian satellite CHAMRAN-1 (61072)).
98766 S2.1b Unknown 1 satellite has been merged with 98795 Altair.
Altair transmitters 435.615 MHz and 435.715 MHz currently are inactive. The merged transmitter at 435.215 MHz is active.

Thanks for the info!
I’m going to add them in DB in the next hours with some temporary NORAD IDs, If you can also share any TLE set we can use, we can start scheduling observations in Network.

Thank you @fredy
With this information the gr-satellites yaml files that are new for this launch are now also updated.
There are TLEs we use. Orbital elements for satellites with numbers 13…24 are acceptable (corrected by STRF), all others obviously require more work on.

Just received my ArcticSat-1 QSL card
Hi Kim,
Thanks for this reminder.
I’ve checked my mailbox which is not affected by yandex blocking.
And, I also got my QSL card for RS74S (ArcticSat-1).
Did they also write on your card “GMSK 9600”?
I received the beacon at 2k4.
I’m wondering how the guys from ASRTU-1 (BJ2CR / RS64S) will distribute their special QSL card planned for first day telemetry.
Daniel
Hello! Please tell me the symbol speed of signals and the period of binary data!
Hi Daniel
I’ve just looked again and yes it’s “GMSK 9600” I also received at 2k4
Same here.
