北斗导航系统移动基准站差分定位算法OA北大核心CSCDCSTPCD
Differential positioning algorithm for mobile base station based on BeiDou navigation system
针对复杂测量环境无法建立固定基准站及进行精密定位的问题,提出一种基于北斗导航系统的移动基准站差分定位算法,即基准站与流动站同时运动并实现高精度差分定位的算法.基于载波相位测量值,在动态短基线条件下,对数据进行站间和星间双差处理,消除接收机钟差以及其他公共误差.对多频观测值进行线性组合,构造双差载波相位超宽巷、宽巷、中巷及窄巷观测量.对上述观测量进行窗口滑动均值滤波并采用逐级模糊度确定法固定整周模糊度,即沿着从超宽巷到窄巷的顺序依次求解整周模糊度.…查看全部>>
Aiming at the problem that fixed measurement environments cannot establish a fixed base station and thus cannot carry out precise positioning,a differential positioning algorithm for mobile base station based on BeiDou navigation system was proposed,which means achieving high-precise differential positioning while the base station and the rover both moving.Based on the carrier phase measurement,under the condition of dynamic short baseline,the datum were int…查看全部>>
