Headline Details: A 580x880x680mm microsat.The main mission goal 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. Only for short experiments the UHF modem will be used. Using BIROSí UHF modem, the communication 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. The satellite UHF modem will have a digipeater function to mirror a signal to another satellite or ground station. Furthermore it will provide a beacon signal for radio amateurs. Proposing a 4k8 GMSK downlink on UHF using the Mobitex protocol. Requesting 435.950MHz.Planning a 500km high SSO launch from Satish Dhawan Space Center, Sriharikota in April 2016.
