Operation of Onboard Data Handling System in Different Switching Modes for RVSAT-1

RVSAT-1 is a 2U nanosatellite based on cubesat standards with astrobiological payload. RVSAT-1 also aims to deorbit and does not contribute to space debris. RVSAT-1 is designed to undergo five different operational modes. The autonomous switching is preferred over manual switching, since it does not require telecommand and hence the modes can be switched even when the satellite is not in Line Of Sight. This paper discusses the different operational modes and the operations of On Board Data Handling (OBDH) system during transition of modes throughout the lifespan of RVSAT-1.
