BIROS / BEESAT-4 update

The main (non-amateur) mission goal of the BIROS satellite is the detection of thermal hot spots like forest fire or volcano activities. The main payload of the BIROS satellite will be a multispectral camera system. The satellite itself is a 3-axes stabilized platform with reaction wheels and magnetorquers. The standard downlink and uplink is a wire S-Band and does not use amateur-satellite service bands.

Only for short experiments the UHF modem will be used. Using BIROS’ UHF modem, the communication (435.950 MHz) between amateur satellite BEESAT-4 and ground stations should be monitored. The same experiment will be done for communication between BIROS and ground stations (BEESAT-4 will be monitoring), until BEESAT-4 drifted too far away from BIROS.
After the experiment is ended the satellite’s UHF modem can be used by amateurs as a digipeater. Furthermore it will provide a beacon signal for radio amateurs.

BIROS will carry onboard the picosatellite BEESAT-4 and release it through a spring mechanism after the successful check-out and commissioning of all relevant BIROS subsystems (6 weeks).
