The satellite is alive.  Big congratulations to the Mir-Sat-1 team.  Jean Marc has received telemetry and is handling media inquiries but will no doubt make an announcement when he comes up for air.

I heard the spacecraft on it's most recent pass over North America but I can't decode the packet I received.  So it is on.  I am not sure of the beacon frequency because I only heard one packet, but it is not continuous.  It is probably every few minutes.  So track it and see what you can hear.

Initially during commissioning I expect it to be in telemetry mode only.  We will have to wait and see how long it takes to turn on the PacSat broadcasts or the Digipeter.  It is not listening for uplinks, so don't transmit to the spacecraft.

Chris + Team,

Any updates on the MIR-SAT1 radio?

I tried to listen on the first two passes of the ISS this AM - heard nothing:

436.925 MHz @ 9600 baud

Also, the SatNogs dashboard is reporting zero telemetry packets.

What is the ETA for turning on the things?

Mir-Sat-1 will be deployed from the ISS Tuesday at 10.55 UTC by JAXA.  This satellite will support an AX25 digipeter and images broadcast with the pacsat protocol.  The images will be taken by its camera and stored in the onboard file system.  Amateur stations will be able to request the directory of files and request the broadcast of images using a suitable ground station.  Many thanks to Jean Marc and the amateurs on Mauritius for collaborating and getting Amateur Radio included on this mission.

I have updated the Pacsat ground station to support Mir-Sat-1.  See my post here: https://www.g0kla.com/workbench/2021-06-18.php.  If you use a GNU Radio tool chain then Dani has updated gr-satellites to support Mir-Sat-1.  SatNogs is adding Mir-Sat-1 to its decoders and will also store the received telemetry.  If you come up with your own decoder then please forward to SatNogs.

Use the ISS Keps initially to track it.  There is an award for the first telemetry.

Feel free to ask any questions.
