| Abstract: | The relations between the accuracy of COMPASS pseudorange observations and elevation angles of satellite are studied, and the pseudorange point positioning accuracy of the constellation which contains 4 Geostationary Orbit（GEO）satellites and 5 Inclined Geo-synchronization Orbit（IGSO）satellites is analyzed. The results demonstrate multi-path effects of COMPASS pseudorange and observation noise are about 0-3 m, and their accuracies are about 0.3-0.7 m. At the higher elevation angles, multi-path effects and observation noise are the smaller, and both of the multi path effects and observation noise on all GEO satellites are smaller than those on IGSO satellites. The COMPASS pseudorange point positioning accuracy（RMS）in the N, E and U directions are about 3.33, 3.45 and 8.84 m, respectively. |
