| Abstract: | The impact of ephemeris on single point positioning and relative positioning is introduced in this paper,sequently calculates and analyzes an example for the rapid precise ephemeris and final precise ephemeris respectively using observed data offered by IGS tracking stations.The conclusion shows the feasibility that IGS rapid ephemeris can commonly replace the final ephemeris. |

| Keywords: | Final precise ephemeris rapid precise ephemeris zero-difference model double-difference model |
