The Simulation of GEO Satellite Trajectory
【摘要】：The space segment of modern GNSS usually is a mixed constellation, which consists of MEO, GEO and IGSO satellites. During the development of satellite signal simulation system, the simulation of trajectory of satellite is necessary. For GEO satellite, the orbital motion equation in ECEF coordinates is derived, and the position and velocity of satellite are obtained in terms of Runge-Kutta numerical algorithm to realize the required trajectory simulation. The validity is verified with real BD1 and CAPS satellites measurements.
