GPS Satellite Simulator Validation Testing for the GPS JPO

Shelton Green, Craig Stroing, Edward Weston and Barbara Wheaton

Abstract:	Military test organizations use GPS simulators to perform laboratory testing of receivers for the GPS Joint Program Office (JPO). The JPO’s User Equipment Test Branch (CZUT) established the Satellite Simulator Control Working Group (SSCWG) to insure that the simulators being used by the test organizations could generate the required GPS RF signals. The SSCWG created the GPS simulator Enhanced Validation Test Plan (EVTP) in order to meet these obligations and is in the process of using it to validate and characterize the simulators belonging to its member test organizations. To date, SPAWAR Systems Center in San Diego (SSC-SD), Naval Air Warfare Center – Weapons Division (NAWC-WD) at China Lake, the Electronic Proving Grounds (EPG) at Fort Huachuca and the Central Inertial Guidance Test Facility (CIGTF) at Holloman AFB have completed the EVTP on their simulators. The other SSCWG member organizations, CECOM and the Naval Research Laboratory, are in the process of conducting the test. This paper describes the EVTP and presents a summary of test results. This includes discussion of the Test Plan development, test approach, primary test scenarios, and data collection, reduction and analysis methodology.
