Abstract: | Real-time reading of Beidou satellite ephemeris is realized in the paper, the satellite orbit structure parameters are updated by C language programming to calculate the Beidou satellite position. The calculation results were compared with the precise ephemeris provided by IGS data center of Wuhan University to evaluate the real-time satellite position results. The maximum error is no more than 3.5 meters, which meets the needs of practical application. |
