摘要
微小卫星星座在遥感、通讯、导航和深空探测领域具有巨大潜力,对于地区的经济发展、环保监督和应急预警都有重要意义.本文依托低轨Walker星座展开研究,通过分析轨道摄动影响下的传统星座构型,得到单颗卫星的地面覆盖面积.利用覆盖带理论建立星座构型设计模型,分析卫星星座的区域覆盖能力,实现星座构型参数的优化.以京津冀地区观测星座构型全时段设计为例,通过理论分析与STK软件仿真分析结果对比,验证了提出的星座构型设计方法的可行性和有效性,得到了京津冀地区观测卫星星座构型的最优参数.
Abstract
Microsatellite constellations have great potential in remote sensing,communication,navigation and deep space exploration,and are of great significance to regional economic development,environmental protection supervision and emergency warning.Based on the low-orbit Walker constellation,this paper analyzes the traditional constellation configuration and satellite orbit perturbation,and obtains the ground coverage area of a single satellite.The covering band theory is used to establish the constellation configuration design model,analyze the regional coverage capability of satellite constellation,and realize the optimization of constellation configuration parameters.Taking the design of the observation constellation configuration in the Beijing-Tianjin-Hebei region as an example,the feasibility and effectiveness of the proposed design method was verified by comparing the theoretical analysis with the simulation analysis results of STK software,and the optimal parameters of observation satellite constellation configuration in the Beijing-Tianjin-Hebei region were obtained.
