Realization of Low Inclination Satellites Constellation Optimization Based on GA
Aiming at the problem of multi-coverage of hot regions,a design scheme of common ground track constellation with regression orbit attribute is applied,and a design method based on genetic algo-rithm(GA)for optimization of the orbital parameters of a single satellite and analytic method for solving the orbital parameters of a constellation is proposed in this paper.Firstly,a regression orbit model for muti-coverage of hot region is established.Secondly,by taking the optimal coverage effect of a hot re-gion as the performance index,genetic algorithm(GA)is used to optimize and solve the orbit parameters of a single satellite.Finally,the orbit parameters of the constellation are solved by analytical method.The results of theoretical analysis and simulation totally show that the design method can achieve peri-odic multi-coverage of hot regions and higher time resolution ratio,which present fairly good engineer-ing application value.
