摘　　要：在沿岸及海岛(礁)测量区域,利用TEQC软件,对几种常用测量型接收机采集的控制测量数据进行质量分析。通过从观测时间长度、卫星信号的信噪比、观测卫星总数、多路径效应、数据可利用率和周跳值等几个方面进行比较,选取了多路径效应值较大的观测数据进行了PPP解算,得出了一些有益结论,为今后的海洋控制测量作业提供良好的建议。The quality of the control survey data collected by several common measuring receivers in coastwise and island survey coverage is analyzed by TEQC software.The comparison is conducted in several aspects,such as observation time,signal-noise ratio of the satellite signals,number of observation satellite,multipath delay,available rate of data,size of cycle-slip and so on.We process the data with high MP and CSR,and obtain some useful conclusion to provide a good advice for hydrographic control surveys.
