RESEARCH ON CYCLE SLIP DETECTION METHODS FOR UN-DIFFERENCED GPS DATA
|
Abstract:
We present an analysis of two cycle slip detection methods: TurboEdit and TECR.The effects of cycle slip detection with these two methods during ionospheric disturbance are studied.Cycle slip detection experiments were carried out by selecting observed data with different sampling intervals and different levels of ionospheric activity.The results show that,for the un-differenced GPS data,the TurboEdit combination cannot detect wide lane cycle slips within 6 cycles,while the TECR method can detect any combination of cycle slips,but the sampling interval must be less than or equal to 1 second.
