ascending node
2.In this paper, the impacts of 4 types of LEO orbit parameters—argument of latitude(AOL), right ascension of ascending node(RAAN), orbit height and inclination—on the distribution and number of occultation events a single LEO satellite observed are discussed through simulation and some conclusions are drawn.
4.In view of the regression characteristic and the configuration maintenance demand of the regional coverage satellite constellation, the constellation configuration is optimized using the linear relations between the semi-major axis and inclination and the rates of change of the ascending node right ascension and phase, which enhance the long-term stability of the satellite constellation configuration, simultaneously the sub-stellar and the phase are controlled through changing the deviations of the semi-major axis and the inclination.
