Abstract

This paper describes the implementation and first on flight results of a GPS and a star imaging system (SIS) using a common transputer processing unit. The described transputer navigation unit has been integrated on PoSAT-1, the first Portuguese satellite, which was launched into LEO on September 26, 1993. The authors present the possible employment of these systems, the SIS, the GPS, and the parallel nature of transputer processing, as a powerful and efficient navigation unit for small and low earth orbiting satellites.
