| Abstract: | According to outlier detection theory this, paper proposes a new algorithm useing the positioning domain to detect the cycle slip in satellite-borne GPS carrier phase measurements, which is defined as varying residual in epoch-by-epoch carrier phase measurements(VAREC). The results indicate that the algorithm can detect all outliers provided by more than 5 GPS satellites tracked by the satellite-borne receiver simultaneously. |
