近地引力波编队构型设计与初始化方法研究

The near-Earth miniaturized gravitational wave detection formation has a short development period and low cost. Therefore, it is suitable for the verification of key technologies in the early stage of gravitational wave projects and has important engineering application value. Compared with the deep space environment, the inter-satellite distance of the formation of near-Earth gravitational waves tends to fluctuate greatly under the influence of the perturbation force, posing a challenge to the natural stable formation configuration design and accurate initialization. Based on the orbital dynamics and relative motion dynamics under the two-body gravitational field, this paper makes a preliminary design of the equilateral triangle formation configuration. Taking the long-term stability of the configuration as the goal, the natural stable configuration under perturbation conditions is solved with the perturbation analysis theory and the numerical search method of intelligent optimization, which provides a stable configuration design plan for the formation of near-Earth gravitational wave detection. Finally, for the precise initialization of the detection configuration, the global optimal differential correction strategy is explored, and the high- precision construction of the near-Earth gravitational wave detection formation is realized.
