Abstract:	The paper describes a new and innovative reference system architecture to be used in the Sight test evaluation of navigation equipment. The Submeter Accuracy Reference System (SARS) will provide submeter position and cm/s velocity accuracy in near real-time, in a highly dynamic environment and under GPS jamming conditions. Systems related issues, such as deployment capability for range applications, ease of operation, low size, power and cost were considered in a trade-off analysis. The proposed architecture uses a frequency shifted GPS-like signal and exploits the transmitter signal characteristics to mitigate the effects of dynamics and jamming. The architecture also employs a novel kinematic carrier phase processing technique to obtain the navigation and attitude solution. The proposed architecture includes a modular transmitter/receiver configuration capable of processing GPS and frequency shifted GPS-like signals, simultaneously or independently, depending on the test mode. The paper discusses the SARS requirements and presents the results of a recently completed study demonstrating the feasibility of the architecture. The study also considered techniques for the mitigation of aircraft vibration and flexure effects in high dynamics.
