摘要
结合在测量工程中应用ASHTECH和TRIMBLEGPS接收机的实践 ,本文主要说明了GPS数据处理过程中 ,对基线向量解算的人为干预处理、独立边的选取、闭合环检查、限制GPS网的投影长度变形及其成果的检验问题。
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.
