Implementation of FMEA to improve the reliability of GEO satellite payload

In this paper, general procedure of failure modes and effects analysis (FMEA) for designing a GEO satellite payload has been implemented and it has been shown that this analysis serves as a useful tool to identify critical items of the product which leads to consider modifications for preventing or compensating failures and finally improving product reliability. The overall actions which have been done using FMEA technique and the design of a redundancy scheme with regard to cost, practical limitations, and system complications lead to an improvement in reliability from 79.15% to 97.52% for preassigned lifetime which can satisfy the desired requirement for this kind of products.
