An Improved Cycle Slip Detection Based on Turbo EditMethod for Dual-frequency GPS Receiver

  • Objective Considering the limitations of TurboEdit,an improved cycle-slip detection method namedthe two-step method is proposed for dual-frequency GPS receivers.Firstly,the new method detectswide-lane cycle slips based on test values computed from a forward-backward moving window for MW(Melborne-Wubbena)combination observations,and then detects cycle slips in the carrier phase L1based on the check conditions extracted from a moving window of the first-order difference quotient ofPIR(phase ionospheric residual)combination observations which have been removed wide-lane cycleslips.The experimental results show that the new method can effectively suppress noise,and superiorto TurboEdit for detecting small cycle slips.It can also explore when cycle-slips exist in both two car-rier phases.
