A Coordination Control Method for Stationkeeping of Regressive Orbit Regional Coverage Satellite Constellation

Studied the characteristic of the regressive orbit and its application in the regional coverage constellation, and designed a regional coverage constellation. Through studying on the equation of motion of substellar track, it may realize the correction about the deviation of the substellar track through controlling the deviation of ascending node right ascension, and through controlling the deviation of phase in the along-track direction, it may realize the correction about the relative positions between the regional coverage constellation satellites. Using the deviation of semi-major axis and inclination have realized to control the rate of change of the deviation of ascending node right ascension and phase together. Simulation results for the regional coverage constellation confirm that the control method is valid.
