A fault tolerance design on onboard computer (OBC) is proposed that allows commercial-off-the-shelf (COTS) devices to be incorporated into dual processing modules of onboard computer. The processing module is composed of 32-bit ARM RISC processor and other COTS devices. As well as, a set of fault handling mechanisms is implemented in the computer system. The onboard software was organized around a set of processes that communicate between each other through a routing process. The fault tolerant onboard computer has excellent data processing capability and is enough to meet the demands of the extremely tight constraints on mass, volume, power consumption and space environmental conditions.
