Abstract:In order to solve the problem that the carrier-to-noise ratio(CNR) data of existing cycle slip detection methods is not effectively utilized, based on influence analysis of the type of BDS on the MW combination observation value, we propose a CNR-weighted MW combination cycle slip-detection model based on the traditional TurboEdit algorithm for different types of BDS satellites. The test results show that the method is superior to the traditional TurboEdit algorithm in effectively reducing the cycle slip miss-detection and false-detection caused by system bias for IGSO and MEO satellites of BDS-2.
