On the satellite system on a satellite's orbit, human preservation is impossible. Consequently, the reliability demand in a satellite system can search for a very high level as compared with ground apparatus. Satellite system requires very high reliability as compared with ground system. This is one of the big factors of a cost rise of the whole system. This paper describes the method which is neither the quality control-technique of each element, nor the technique of adding a redundant system on the design process of satellite system We examine the space system which performs functional preservation "soft fail" with self-recovery.
