Problems solved by technology

[0005] The purpose of the present invention is to address the shortcomings of the above-mentioned prior art, and propose a satellite constellation configuration parameter optimization method for regional non-uniform service coverage, which is used to solve the problem of facing the coverage target area in the existing satellite constellation configuration design. When there is a non-uniform service demand, no attention is paid to the matching relationship between the service rate provided by the satellite constellation to the target area and the actual service demand rate in the area

Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] refer to figure 1 , the implementation steps of the present invention are further described in detail.

[0032] In the embodiment of the present invention, the satellite constellation coverage target area is selected as China's land area, and the OneWeb satellite constellation is used as a reference to optimize the configuration parameters of the satellite constellation.

[0033] Step 1, generate a non-uniform business demand model in the region.

[0034] The embodiment of the present invention divides the covered target area, that is, China's land area, into 1030 effective 1°×1° grids according to latitude and longitude (latitude: 5°-53°N, longitude: 74°-134°E). The population data obtained from the National Bureau of Statistics is processed and allocated to 1030 grids to obtain the population of each grid, and it is assumed...

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.

Description

technical field [0001] The present invention relates to the technical field of communication, and further relates to a satellite constellation configuration parameter optimization method for regional non-uniform service coverage in the technical field of satellite communication. The invention can be used to optimize the configuration parameters of the constructed satellite constellation. Background technique [0002] The focus of attention on satellite constellation configuration is its ability to serve business needs. The design of the satellite constellation configuration is to select the appropriate orbit form according to the requirements of the coverage mission, and construct the satellite constellation system by optimizing the configuration parameters of the satellite constellation, so as to meet the requirements of the coverage mission with the minimum space segment cost. In the current satellite constellation configuration design methods, there are many design metho...
