Optimization Method of Satellite Constellation Configuration Parameters for Non-uniform Service Coverage

Abstract

The invention discloses a satellite constellation configuration parameter optimization method for regional non-uniform service coverage, and the specific steps of realization are: 1) generating a non-uniform service demand model in the region; 2) generating a service rate model provided by the satellite constellation to the region ; 3) Constructing the service coverage performance function; 4) Establishing a multi-objective optimization model; 5) Optimizing the configuration parameters of the satellite constellation by using the genetic algorithm; 6) Obtaining the optimized configuration parameters of the satellite constellation. The present invention constructs a service coverage performance function according to the service rate of the satellite constellation to cover the target area and the business demand of the area, and considers the deployment cost to establish a multi-objective optimization model, and uses a genetic algorithm to optimize the configuration parameters of the satellite constellation, thereby realizing the maximum coverage of the satellite constellation to the area. The service coverage performance and the minimization of satellite constellation deployment cost can be used for the optimization of satellite constellation configuration parameters.
