Abstract The principle and method of cycle slip detection and repair by using Kalman filtering are introduced, and the steps of solution are provided in detail. Furthermore, by taking prestical observation data as the example, this paper validates the usability of Kalman filtering in cycle slip detection and repair.The solution results indicate that when Kalman filtering detects the cycle slip in the nondifferential carrier phase observation data,the fluctuation of noise is very small and then cycle slip is easy to be found.Even if there is small cycle slip,Kalman filtering can also detect and repair it.
Key words :
