BeeSAT-2 and SOMP deployed and active

Posted on by

The two satellites BeeSAT-2 and SOMP are successfully deployed and are active the first CW and DATA signals are received. I myself was able to receive these satellites during the pass at 15:02 CEST / 13:02 UTC on April 21, 2013. Congratulations TU Dresden (SOMP) and TU Berlin (BeeSAT).

Preliminary object information 2013-015x series

Soyuz 2.1a 19-04-2013 10:00 UTCAfter the successful launch of a Soyuz-2.1a with BeeSAT-2, BeeSAT-3, SOMP, OSSI-1 and main payload: Bion-M1 here is some object information that I could find during the last couple of days regarding the possible objects that apply.

With this information I have tried to receive data from OSSI-1 on 145.980 and also on 437.525, but no luck so far.

BION-M1
Object information: 39130 2013-015A

BION-M1

It was separated from BION-M1 at 16:13:50 UTC on April 19
Object information: 39131 2013-015B (probably)

The upper stage of the Soyuz 2.1a rocket

The numbers 39132 to 39136 have been reserved for the other satellites on this launch.
But these satellites are still attached to BION M1. They are expected to be separated from BION M1 in two batches on Sunday starting at 08:15 (AIST and Dove 2) and starting at 11:00 UTC (BEESAT 3, BEESAT 2 and SOMP).

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.

RAX-2 TLM 01-04-2013 18:05 UTC

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.

Cubebug-1

Posted on by

The Capitán Beto (AKA CubeBug-1)

CubeBug-1 ModelCubeBug-1 is the first technology demonstration mission for a new cubesat platform design (mechanics, hardware and software) intended to be released as Open Source and Open Hardware for its use in Amateur projects, University projects and research labs. This project is sponsored by the Argentinian Ministry of Science, Technology and Productive Innovation, INVAP S.E., Satellogic S.A., and Radio Club Bariloche.

As payload on this first mission, some custom designed components will be tested: an ARM based on-board computer, a nano-reaction wheel with its driver circuit and a low resolution camera, all based on COTS components.

After the technology demonstration part of the mission is over, the satellite will enter a mode that will include services to the Amateur radio community, including a Digipeter and science data downloads from the payload.

Finally successful in decoding STRaND-1 telemetry.

After experimenting with different 9600 baud packet decoders I am finally able to the decode the satellites telemetry. The combination of FCD Pro+ -> Audio mixer -> MiXW -> VSP Manager -> Online Kiss made it possible to produce the following image.
