Abstract
Two GPS system configurations for precise shipborne and land static differential GPS (DGPS) positioning were evaluated for accuracy of code and carrier phase measurements. Tested were the Ashtech L-X11 and the Magnavox 4200D receivers. Real-time (using receiver internal software) and post-mission (using the University of Calgary C3NAV software) positions were calculated. These positions were intercompared, and also compared with positions from a microwave positioning system. The RMS agreement between real-time DGPS, post-mission DGPS, and microwave positioning was the the 2 to 4 metre level, as expected. Conclusions on the performance of the equipment utilized during the trials are presented.
