Performance Comparison of Two Methods of Multiple Reference Stations DGPS

Richard Barker and Dariusz Lapucha

Abstract:	This paper addresses the performance of the two methods of multiple reference DGPS. In the first method, reference network differential corrections are applied to the range observations from the user GPS receiver. The individual reference station solutions are then combined in the position domain to provide a composite solution. In the second method, the reference station differential corrections are combined in correction domain to provide the set of localized composite corrections in RTCM SC- 104 format. These corrections are fed to the GPS receiver operating in differential mode. The results presented here show that both methods enable maintaining submeter horizontal position accuracy at distances up to 1000 km from the reference. stations.
