GPS Receiver Testing Issues and Techniques

Kenea C. Maraffio

Abstract:	Characterization and system integration of GPS receivers requires the use of complex hardware-in-the-loop test environments running satellite signal simulators and other dynamic simulations. These test environments am expensive to purchase and maintain. NAWCWPNS has developed a distributed processing methodology using computer networking to reduce the expense of GPS receiver characterization and integration. NA WC WPNS customers now have the option of performing tests on-site or at a local site separate from the Navigation Laboratory. This paper begins with an overview of the types of GPS receiver tests and the issues associated with those tests. Then, descriptions of the Navigation Laboratory and the techniques it incorporates to resolve these issues are given as a case study of the distributive processing test environment. Laboratory enhancements being developed in response to broadening customer needs are also presented. The paper concludes with a summary of GPS satellite simulator lessons learned.
