摘　　要：文中针对GPS静态定位中误差产生的各种来源,重点讨论了影响矿区进行GPS定位精度的各种因素。在考虑PDOP值大小和坐标转换因素影响的前提下,根据GPS静态绝对与相对两种定位方法的测试方案和成果进行了统计和比较,就其对GPS单频接收机的定位精度情况进行了分析,对于矿区GPS相对静态定位得出了一定的结论。In view of various kinds of causes why errors take place in GPS static positioning,the paper elaborates factors that affect GPS positioning accuracy in mine areas firstly.Under a prerequisite of effect caused by such factors as PDOP values and coordinate transformation etc.and based on statistics and comparison made to the tests and results of two GPS static positioning methods,i.e.absolute and relative methods,the positioning accuracy of the GPS single-frequency receivers is analyzed and practical conclusions on GPS static relative positioning in mine areas are also drawn in the paper.
