Abstract

To evaluate the satellite orbit and clock errors of COMPASS, we compare the difference between broadcast ephemeris and precise orbits and clocks. Results show that the orbit errors present certain periodicity for GEO and IGSO satellites. The SISRE of COMPASS is larger than GPS and GLONASS overall. However, the broadcast ephemeris of COMPASS appears regular changes in short time. Based on this, we establish different rapid correction models for COMPASS satellite orbits and clocks error. Analysis proves that the result performs well when the length of the arc for the model is shorter than 30 min, and the linear model is best for satellite clock corrections. By using this model, we predict the corrections of the satellite orbits and clocks, which is used for pseudo-range and carrier phase positioning. Results show that the positioning accuracy is on the same level with precise products for pseudo-range and carrier phase, while the convergence time is longer. This research provides an important basis for the realization of sub-meter wide area augmentation of COMPASS.
