Below a SDR spectrum with the MASAT-1 data. It first sends CW and afterwards a GFSK signal.

And here a telemetry audio fragment.

With the MASAT-1 Ground station decoder you received raw data in the following format:

PACKET 00 9E 09 02 50 20 13 10 13 19 21 06 13 4B 2A 03 01 00 00 00 00 00 00 00 00\

When applying that data to the MASAT-1 decoder made by Mike DK3WN you get the following output.

OSSI-1

With the help of the below TLE data I am listening to OSSI-1 this evening. But after three passes I haven’t heard anything from this new Cubesat. I have listened on both 145.980 and 437.525 (Kenwood TS-711 on VHF and FUNcube Dongle Pro+ on UHF)

Telemetry decoding

Posted on by

This evening we did some telemetry decoding.

April 1, 2013 17:50 UTC

First CubeSat we gave a try was STRaND-1, but it wasn’t sending any data this evening (April 1, 2013 17:50 UTC). When I looked at the Satblog from DK3WN it seems that STRaND-1 wasn’t heard the whole day. Lets hope noting is wrong with the CubeSat.

April 1, 2013 18:05 UTC

RAX-2 is sending telemetry loud and clear, and the combination FUNcube Dongle Pro+, Orbitron and SDR# are doing a great job in controlling Doppler thanks to a great Doppler control plugin that can be part of SDR#.

RAX-2 SDRSharp

RAX-2 is sending every 20s a 9k6 data burst that can be decoded with the decode software from Mike DK3WN. During this pass I received over 60 packets and in the below image you can see the results.

Here is an example of a KISS frame that is received from RAX-2, nice to see the error that RAX-2 is using RAX-1 as Call.

MASAT-1 sends a two tone signal

MASAT-1 Audio Spectrum

This signal can be decoded with the telemetry software that is available on MASAT-1 website. After that you can use the log file with a decoder program from DK3WN and this produces the following output.

When you want to experiment with receiving telemetry, take a look at my soundcard page and give it a try.

OSCAR Number Administrator Bill Tynan, W3XO reports, “Congratulations on the successful launch of the MaSat-1 Cubesat that the team at Budapest University of Technology and Economics have been responsible for designing, building and testing.

“Since you have met all of the requirements for being issued an OSCAR number, including coordination through IARU and requesting an OSCAR number, I, under authority vested in me by the President of AMSAT-NA, do hereby name MaSat-1 as MagyarSat-OSCAR-72 or MO-72.” Bill concludes, “I, and all at AMSAT-NA wish MagyarSat-OSCAR-72 great success in fulfilling all of its mission objectives.”

[PE0SAT thanks Bill Tynan, W3XO for the above information]
