Efficient method of cycle slips detection for dual-frequency GPS data
(Survey Department of Transportation College, Southeast University, Nanjing 210096, China)
Abstract: An algorithm has been developed from various exiting techniques, that provides fully automatic cycle-slip detection at the data preprocessing stage. This algorithm, called pair linear combination, operates on undifferenced or double-differenced, dual frequency carrier phase data, and requires the sampling interval is short. Test results carried out in a variety of situations including static and kinematic modes, short and long baseline situation, and low and high data rates were presented.
