Simulated Inertial GPS Navigation Laboratory (SIGNal)

Marvin May and Robert Mullen

Abstract:	Embedded GPS-lnertials have hit the street with their wheels turning and are likely to dominate the navigation market. Already most high performance military aircraft and precision guided munitions have committed to the adoption of these systems. Paralleling these developments, has been the widespread recognition of the importance of GPS user equipment test facilities (UETF) which include satellite simulator systems. This paper addresses how UETFs can be utilized to aid in the development and testing of embedded INS systems. The methodology for creating raw inertial sensor assembly outputs in a manner consistent with the simulated satellite signals under arbitrary user dynamics is discussed. Algorithms and interfacing techniques developed to generate simulated inertial data while minimizing senescence, latency, quantization and calibration errors are summarized. The hardware configurations as formulated for specific embedded inertials are shown.
