A High Accuracy Relative DGPS Antenna Baseline Measurement System for Sensor Stabilization

Chris Bartone, Frank van Graas and Tom Arthur

Abstract:	A high accuracy relative differential GPS (RDGPS) Antenna Baseline Measurement System (ABMS) was developed and presented here for applications for sensor stabilization. The systems utilized GPS L1 and L2 measurements and an inertial navigation system (INS); the INS is used to initialize the widelane GPS carrier phase ambiguities and transfer to the GPS single frequency ambiguities. Parity space methods are used to assess the solved baseline accuracy. Flight tests conducted on the Ohio University DC-3 aircraft, with an antenna baseline of 14 m were used for demonstration of the ABMS performance. This is believed to be the first flight demonstration of initializing the GPS L1, and L2 carrier phase ambiguities with an INS, and the first demonstration of high rate (100 Hz) GPS carrier phase RDGPS for high accuracy on the order of [4,4,10] mm.
