Connection Planning Method Between LEO Communication Constellation and Earth Station

A connection planning method between LEO communication constellation and earth station was proposed.Considering the large number of LEO communication constellation satellites, it is diffi cult to directly establish the connection planning method between LEO communication constellation and multiple earth stations.The connection planning method between single satellite and single earth station, the connection planning method between satellite constellation and single earth station, the connection planning method between satellite constellation and multiple earth stations were established.The former planning method is the basis of the latter planning method, which is the expansion of the former planning method, and fi nally forms a connection planning method between LEO communication constellation and multiple earth stations.A typical simulation example showed that in the process of connecting between the earth station and the satellite constellation, the elevation from the earth station to the satellite was not
