Abstract
On the basis of the multiple-frequency observation combination theory, the triple-frequency MW and Geometry-free combination and the triple-frequency pseudorange/carrier phase combination cycle-slip detection model have been deduced respectively. Using the Compass triple-frequency observation data, under the circumstances of different sampling intervals, the detection effects of the two methods have been studied in cases of cycle slip occurring on a single frequency and multiple frequencies. The results have shown that when the sampling interval is 1 s, both the two methods have good results; when sampling interval is 10 s, the MW and Geometry-free combination is better; when the sampling interval is 30 s, both the two methods are affected in some extent. Then we have the conclusion, in the process of observation, the sampling interval should be set smaller than 10 s which is beneficial for cycle slip detection and repair. And in most cases, the MW and Geometry-free combination is more effective.
