The Use of Commercial Technology for Spaceborne GPS Receiver Design

M.J.Unwin, M.K.Oldfield, C.I.Underwood

Abstract:	The use of commercial off-the-shelf (COTS) sub-systems may not be acceptable for many space programmes due to reliability or radiation tolerance issues. At the same time, fully space-designed and qualified technology can be too expensive for small satellite applications. In this paper, the design of a GPS receiver for space applications manufactured from commercial parts is described. The testing of the core components under radiation can help demonstrate the suitability of the technology for spaceborne applications while maintaining the low cost approach. The SGR designed and built at Surrey Space Centre is planned for several forthcoming satellites and these are introduced in this paper.
