The invention provides a lightning orbit constellation construction method and system for meteorological exploration, and the method comprises the steps: selecting the geographic longitude of an ascending node of an orbit according to the basic parameters and observation demands of the lightning orbit, and determining the allowable range of the geographic longitude of the ascending node; determining the working height and the information acquisition capability of each orbit of the satellite according to the dynamic coverage capability of the lightning orbit satellite; according to the characteristics of east and west orbits of a lightning orbit satellite, fixed ground stations are respectively selected from an east orbit and a west orbit to receive satellite meteorological data; constructing a three-dimensional constellation formed by two groups of four satellites according to a double-satellite positioning requirement, and meeting a preset region task area three-dimensional positioning requirement; a three-satellite elastic emergency mode is set, and when a single-satellite fault occurs, all-day three-dimensional detection of a preset area by three satellites is realized through temporary orbit maneuver. According to the constellation configuration design, the main task of the extreme region is fully considered, the coverage of the region in China is considered through the development of the climbing section, and the acquisition capability of short-time multi-scale meteorological data is improved.
本发明提供了一种面向气象探测的闪电轨道星座构建方法和系统,包括:根据闪电轨道的基本参数和观测需求,选择轨道升交点地理经度,确定升交点地理经度允许的范围;根据闪电轨道卫星动态覆盖能力,确定卫星每轨的工作高度和信息获取能力;根据闪电轨道卫星东西轨道的特点,在东轨、西轨分别选择固定地面站接收卫星气象数据;根据双星定位需求,构建两组四星组成的立体星座,满足预设地区任务区域立体定位需求;设置三星弹性应急模式,在出现单星故障时,通过临时轨道机动,实现三星对预设地区的全天立体探测。本发明星座构型设计充分考虑了极端地区主任务,并通过对爬升段的开发,兼顾了我国区域的覆盖,增加了短时多尺度气象数据的获取能力。
