Error Analysis and Cycle-Slip Detection Research on Satellite-Borne GPS Observation
According to the application characteristics of low-earth-orbit satellite-borne global positioning system (GPS) receiver, the influence of GPS measurement data error on cycle-slip detection is analyzed. Then a modified TurboEdit preprocessing method is proposed. In the modified method, a weighted factor which closely relates to the GPS satellite elevation angle is introduced in the cycle-slip detection process. The weighted factor estimates the error of measurement data based on the variation of GPS elevation angle and establishes a relationship between the cycle-slip detection process and error of measurement data. Then the cycle-slip detection judgment is adjusted by the weighted factor. The modification algorithm not only reduces the fault rate of cycle-slip detection, but also promotes the autonomous ability of orbit determination by increasing the quantity of measurement data that will participate in low-earth-orbit-satellite orbit determination. Finally, the modified algorithm is verified by GPS measurement data of GRACE satellite formation.
