Abstract

The invention provides an earth station and an access method and device thereof, and relates to the technical field of satellite communication. The method comprises the steps: calculating the satellite track segments of all satellites and the satellite track segments of GEO satellites in a to-be-accessed constellation system; determining a target satellite trajectory segment based on the satellitetrajectory segment of each satellite and the satellite trajectory segment of the GEO satellite; accessing a satellite corresponding to the target satellite trajectory segment by using a preset antenna, wherein the preset antenna is a shaped beam antenna or a phased array antenna, so that the technical problem of complex operation when an existing earth station is accessed to a constellation system is solved.

Description

technical field

[0001] The present invention relates to the technical field of satellite communication, in particular to an earth station and its access method and device. Background technique

[0002] The earth station is the ground station for the communication between the ground and the satellite. During the operation of the satellite, the earth station may be within the coverage of multiple satellites at the same time. The selection of the access strategy of the earth station directly affects the performance of the constellation system. Traditional inter-satellite access strategies include distance priority, coverage time priority, comprehensive weighted access, load balancing and other strategies. The realization of the traditional strategy requires the earth station to calculate the ephemeris in real time to find the satellite position, select the satellite that meets the strategy requirements at the current moment, and rotate the antenna to access it. For non-geostat...
