| 摘 要： | 在GPS约束平差中,地面已知点的粗差或错误会导致GPS网形扭曲变形,给平差结果带来失真。当平差结果不能通过可靠性检验时,如何确定含有粗差的点以及估计粗差的大小显得很重要。在论证WGS一84地心平面坐标差与国家(如北京54坐标)或地方参心平面坐标差的一致性基础上,通过分析两种坐标对应点的差值及其比值确定粗差点。

| Abstract: | In the GPS adjustment with conditions,the ground-known point of gross error or error led to the GPS network Deformation,the results brought about distortion by adjustment.When the adjustment can not be the reliability of test results,it appeared very important to determine hoe to contain gross errors point and estimate the size of gross error.On the base of demonstrating the consistency of difference between WGS-84 geocentric coordinate system and the State Plane Coordinate system difference (such as Beijin... |
