Celestial Mechanics: Satellite Constellation, Structure Evolution, Orbit Evolution

Scientific paper

The secular evolution of geometrical structure of satellite constellation is focused. The satellite orbital evolution that caused by the Earth oblate perturbation and the bias of satellite injecting orbit is analyzed. The general character of structure evolution of constellation is discussed. The parameters about the subsatellite point trace of regional constellation and relative position of subsatellite point are used to describe the geometrical structure evolution of constellation. The analysis are given, it to shows that the Earth oblate perturbation will lead the whole shift of constellation geometry, and that the bias of satellite injecting orbit will lead the constellation disorder, in particular, the bias of semi-major axis is very significant, it will determine the stability of regional constellation.
