Abstract

Ephemeris error and clock error are the main source errors of GPS kinematics precise point positioning.Different ephemeris and clock difference will affect the results.The paper using the different ephemeris and clock difference from IGS website to calculate,using Waypoint software to carry on different combination calculation with Car GPS data,and analyzing the position results,has obtained some useful conclusion.
