Abstract:This paper analyzes the accuracy of Galileo spatial signal and Galileo broadcast ephemeris at the present stage. We examine statistics and analyze 30 days health satellite ephemeris in this paper. The results show that the satellite orbit error of FOC and IOV is better than 0.8 m, and the radial error is the smallest. The accuracy of the Galileo satellite clock bias is 1.0 ns. From the spatial signal ranging error to the Galileo satellite, the accuracy of the broadcast ephemeris is better than 1 m, and the accuracy of FOC is equivalent to that of IOV satellite. Single point positioning using broadcast ephemeris precision can reach up to the decimeter level.
