TRI-FREQUENCY CYCLE-SLIP DETECTION AND REPAIR WITH
DIFFERENT SAMPLING INTERVAL
Geospatial Information Institute, Information Engineering University, Zhengzhou 450052
Abstract The normal triplefrequency cycleslip detection and repair algorithms, pseudorange/carrier phase combination and MW & Geometryfree combination, are studied. The detection threshold is given. Using Compass triplefrequency real data, with different sampling intervals, the detection effects of the two methods are analyzed in cases of cycle slips occurring on a single frequency and multiple frequencies. The results have shown that in the process of observation, the sampling interval should be set smaller than 10s which is more beneficial. And the MW Geometryfree combination is usually more effective.
