Abstract:

Autonomous spacecraft control and data processing have recently become realizable due to advanced fault tolerant techniques coupled with the development of very high scale integrated circuits. A method of utilizing present integrated circuit componentry with future technology insertion has been developed on the FTSC Program. The FTSC is designed to support a variety of spaceborne missions with a 95 probability in performance, for five to seven years. Besides easing the ground station scheduling requirements, this capacity increases the overall satellite survivability. The purpose of this paper is to present a concept of achieving the survivability by the utilization of various fault tolerant techniques.
