Abstract

On board computers for spacecrafts are required to work for a long period of time with a very high reliability. The design of such a computer has to be accomplished within major constraints such as use of high reliability components, low power consumption, minimum weight and volume. This paper describes a Radiatioin Hardened (R/H) 80C86 processor based On-Board Computer System (OBCS) for attitude and orbit control of INSAT-2 spacecraft, which incorporates a number of novel fault-tolerant features that do not have major overheads in terms of either hardware or software or processing time. The paper concludes with suggestions for improving the performance of On-Board computers for future spacecrafts.
