Abstract

The invention relates to a satellite constellation implementation method for implementing communication by utilizing a recursive orbit, and the method comprises the steps: a regression period, an orbital semi-major axis, an inclination of an orbit, an eccentricity ratio and an argument of perigee of the orbit are determined; the number of satellites and orbital planes are determined as n; right ascension of ascending node and a mean anomaly of a first satellite are determined, and according to service needs of the satellite, right ascension of ascending node and mean anomaly of following satellites are determined in sequence; a geostationary orbiting satellite network set that needs to be coordinated and the width of a non-geostationary satellite to geostationary satellite interference protection band are determined; all set satellites successively passes the top in the air along a same fixed orbit are seen at any position of the ground, and when multi-coverage is formed, users on theground can see a plurality of satellites; and if satellite trails pass the interference protection band for the geostationary satellite, when present accessed satellite enters the protection band, theusers on the ground switch to another satellite that does not in the protection band to continuously implement communication.

Description

technical field

[0001] The invention relates to the technical field of satellite communication, in particular to a method for implementing a satellite constellation using regressive orbits to implement communication in a non-stationary orbit communication constellation with global coverage. Background technique

[0002] Satellite Internet is the best and possibly the only option in the evolution of the Internet to space. Considering the constraints of the geostationary orbit position, the non-geostationary orbit satellite constellation network will become an important part of the satellite Internet. Currently, several large-scale non-geostationary orbit satellite constellation projects have been put into construction or announced plans around the world. Among them, the O3b network system built by Google uses an equatorial orbit with an inclination of 0ยฐ and an orbital height of 8062Km. There are currently 12 satellites in orbit, and the total throughput of each satellite re...
