摘　　要：本文研究了M型GPS-PDA整机精度的测试方法。通过实测数据分析,得出了该型接收机的静态基线测量、后处理准动态测量、事后RTK面积测量的精度及基线长度与数据采集时间的关系。表明该型GPS-PDA数据采集设备的各项性能指标良好,完全能满足1：1万底图的土地变更调查的精度要求。The testing methods of the precision of M GPS-PDA are studied in this paper. With the analysis of testing data, the survey precision of static baseline, post disposal dynamic and post RTK area, the relation between the length of baseline and the time of data collection are educed. The results indicate that the capability of the GPS-PDA data collection system is quite good, totally meeting the precision requirements of land change survey with 1 ： 10000 base map.
