| 摘 要： | 在GPS／cOMPASS组合差分定位基础上，引入抗差估计方法，通过降权调整合有粗差观测值对定位的影响，利用路测试验，对比RTK的厘米级定位，结果表明：抗差GPS／COMPASS组合实时差分定位优于非抗差定位，平面精度在2．0m左右。

| Abstract: | In order to lower the influence of the observations that contain gross error, GPS/COMPASS real-time differential positioning is done by using robust least square esti- mation, the data from a experiment of vehicle running is analyzed and comparred with RTK results which can be cm level, and the result shows that accuracy of positioning can be 2.0 m level. |
