Abstract:Using a twostage adaptive filter with GPS Doppler measurments to estimate L1 carrier phase, and then the whitening residuals of L1 carrier phase can be obtained comparing it with the actual carrier phase measuments,and considering time correlation of highrate GPS carrier phase measuments error.Finally,by using the whitening residuals the cycle slips in GPS single frequency carrier phase will be detected and repaired. The method is fit for highrate single frequency GPS data. A test using 1 Hz dynamic GPS data reveals that it can detect very small cycle slips.
