Study of the application GPS in opservation data processing

Jia Rei-ying

Abstract

Based on surveying engineering practices of applying ASHTECH and TRIMBLE GPS receivers,this paper mainly describes some problems in GPS observation data processing.The problems include GPS baseline manual calculation,selection of independent baselines,closed loop test,how to limit the projective length error for GPS network,and the examination of adjusted results.
