Abstract:We continuously receive ten days of CNES real-time broadcast data stream information in the state space representation and analyze the integrity of real-time data stream up to 91.769%. Simultaneously, we analyze the accuracy of real-time precision satellite orbit and clock error, which we recover by broadcast ephemeris. The three-dimensional positional accuracy of real-time data stream broadcast by CNES is better than 4.5 cm, and the clock error accuracy is better than 0.09 ns. Then, using the recovered satellite orbits and the clock error, ten-day observation data of ten IGS stations are used to perform precise point positioning calculations. It is concluded that the RTPPP based on the SSR information can achieve 23 min convergence. With a positioning performance of 10 cm accuracy, the single-day solution 3D point accuracy is better than 3 cm.
