The invention relates to the technical field of aerospace, and provides a task satellite scheduling method for an infrared LEO constellation. The method comprises the following steps: projecting an invisible observation angle range of a satellite to a target to earth surface to obtain an undetectable range Db; projecting the maximum detection distance L of the satellite to the earth surface and removing the undetectable range Db to obtain a detectable range D1; projecting the target to the earth surface, and performing detectable analysis of the satellite and the target; screening orbital planes according to the longitude range of ascending nodes of the orbital planes and the geographic position of the target; and screening a task satellite from the screened orbital planes according to the relative motion relation between the satellite and the target and observable conditions. The problems that in the prior art, calculation is complex, on-satellite resource overhead is large and task planning timeliness is low in the task satellite scheduling process are at least partially solved, task satellite optimization efficiency and timeliness are improved, and the method has application value for task satellite scheduling of an infrared LEO constellation and design optimization of the constellation.

    本发明涉及航空航天技术领域,提出了一种红外低轨星座的任务星调度方法,包括:将卫星对于目标的不可见观测角度范围投影到地球表面得到不可测范围Db;将卫星的最大探测距离L投影到地球表面并刨除不可测范围Db得到可探测范围Dl;将目标投影到地球表面进行卫星与目标的可探测分析;由轨道面升交点经度范围与目标的地理位置筛选轨道面;以及由卫星与目标的相对运动关系和可观测条件从筛选出的轨道面中筛选任务星。至少部分解决了现有技术中存在的任务星调度过程中计算较为复杂,星上资源开销大,任务规划时效性低的问题,提升了任务星优选效能和时效性,对于红外低轨星座的任务星调度以及星座的设计优化具有应用价值。
