The COM-Subsystem has the purpose to enable our satellite to communicate with our ground station. Therefor our satellite has VHF, UHF and S-Band antennas. With that COM system, is be able to receive commands we send to our satellite and can send us housekeeping-data as well as pictures that were taken with our cameras.

In addition, our satellite sends an AX.25-beacon in regular intervals via the UHF antenna. This beacon can be received and decoded by any radio amateur operator who has the necessary software. Included in that beacon are data like battery voltage or the operating modes of the subsystems.

The necessary software as well as an installation guide can be found in our download section. It is also possible to send the collected data to us to help us get as much information about our satellite as possible.
