A survey to select microcontroller for Sathyabama satellite´s On Board Computer subsystem

Nanosatellite is the prime focus of many universities those who are interested in space technology. Nanosatellite is popular due to its feasibility and affordability. The primary mission of the Sathyabama nanosatellite is pollution monitoring and data communication to the earth station. For any satellite, On Board Computer (OBC) is considered to be the brain of the satellite. OBC must be designed in such a way that each subsystem should be controlled and monitored by the OBC of the satellite. It is a very important task to choose a microcontroller for OBC in order to make the Sathyabama nanosatellite efficient and powerful in all situations. In this paper, an extensive survey has been made on many international nanosatellites like CubeSat, TUBSAT-N and many national nanosatellites like STUDSAT, PRATHAM etc. to select a right microcontroller for our Sathyabama nanosatellite mission.
