Abstract

The disclosure includes determining a regression period and a semi-major axis of an orbit, inclination, eccentricity and argument of perigee of the orbit; determining both the number of satellites and the number of orbital planes as n; determining right ascension of an ascending node and a mean anomaly of a first satellite, and sequentially determining right ascension of ascending nodes and mean anomalies of subsequent satellites according to satellite service requirements; determining a set of geostationary orbit satellite networks that need to be coordinated, and width of guard band for interference of non-geostationary satellite constellation on geostationary satellite; at any location on the ground, deployed satellites pass overhead successively along fixed trajectory, a user at ground can simultaneously see satellites when multi-coverage is formed; if satellite trajectory crosses the guard band for interference on the geostationary satellite, then when a currently-accessed satellite enters the guard band, user at ground switches to another satellite not in guard band to continue to implement communication.
