周跳的探测与修复

Cycle slip detection and repair

周跳的探测是GPS高精度实时定位的热点问题。结合载波相位和精密伪距,利用无几何距离相位观测方程和宽巷模型来探测周跳。通过算例分析,验证了这种方法的有效性。

Cycle slip detection is the hot question of the high precise real time GPS. Use the freegeometry model and widelane model to detect and repair the cycle slip with the double frequencies and precise pseudorange. At last, an example is given out to illustrate the validity of this method.
