MASAT-1 deorbiting

Dear Radio Amateur / Masat-1 Packet Committer,

Masat-1 ModelWe would like to hereby thank you for supporting our work in the last almost three years by receiving packets of Masat-1 from space. Furthermore, we would like to call your attention to the upcoming deorbiting. Masat-1, the first Hungarian satellite is expected to end its successful mission by burning while entering the Earth’s atmosphere at the beginning of January (current forecast predicts 11 January). The last days and hours of the satellite are especially important for us, providing valuable data for our upcoming endeavours, therefore we would like to keep a close eye on the satellite during the final stage of the mission. For this, we need the help of all those who have already received Masat-1, as the last moments of the satellite’s life may happen anywhere around the Earth. Who will receive the last packets of Masat-1? Following the final moments we will provide an answer to this question, and we also plan to publish a statistics of those stations who received the highest number of packets during the last 168 hours of the mission.

We have published the current version of the JAVA client software on our website.

Wishing you all the best and Merry Christmas, The Masat-1 Development Team.

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.
