| 摘 要： | 采用高崩溃污染率抗差估计，将ＧＰＳ网由ＷＧＳ－８４坐标系下的坐标转换成局部坐标系下的坐标，不仅能识别不稳定的地面基准点，而且对所产生的形变大小能作出近于实际的估计，从而保证了求得的坐标转换参数的可靠性。

| Abstract: | Transforming the coordinates of GPS network from WGS-84 system into a local system in a mining area using robust estimation under high breakdow contamination can not only detect unstable base points, but also estimate their movement values approximately, and consequently make the computing results of coordinate transfoming parameters reliability. |
