摘要
在GPS/COMPASS组合差分定位基础上,引入抗差估计方法,通过降权调整含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。
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.
