GPS Pointing System Performance

Ronald A. Brown, Alan G. Evans

Abstract:	Static and dynamic test results of a real-time GPS pointing determination experiment are presented. The pointing system uses a modified AN/PSN-9 five-channel clear/acquisition (C/A)-code GPS receiver developed by TI that precisely measures the phase difference between two antennas for each GPS satellite. A figure of merit for azimuth and elevation that accounts for a dilution in precision caused by satellite geometry also is presented. Accuracies of the phase difference measurements and the test results are discussed.
