An Infrastructure Architecture for the Testing of GPS Sensors Tightly Coupled with Other Sensor Systems

James W. Youngberg

Abstract:	A legacy of programs has endowed Draper Laboratory with a large inventory of test facilities in predominately mechanical laboratory areas, These include rate tables, multi-axis motion simulators, and centrifuges. In the summer of 1993, Draper purchased a commercial GPS simulator. Its immediate role was to support development of an integrated GPS-INS instrumentation package. Testing the package required assembling a federated electrical (RF, receiver interface, and INS interface) and mechanical (physical motion) environment. Shortly thereafter, characterization testing of an embedded GPS-Doppler system required accessing the simulator output remotely from a cockpit systems integration laboratory. As succeeding programs’ requirements mounted, demands for test system inventory and access grew. Simultaneously, an interconnection infrastructure began to evolve. This paper discusses the architecture, technical challenges, features, and benefits of the evolving infrastructure.
