在战争中为了避开敌方军事卫星的侦查,需要对其过顶时间进行预警.对于参数公开的卫星,可以通过根数来进行准确的预报.而对于参数未知的卫星,提出了一种根据过往观测数据来对卫星过顶时间进行预测的思路:将卫星与地球之间复杂的三维耦合运动进行降维,并且以地面为参考系,发现卫星星下点运动轨迹具有高度的周期性·根据这种思路,可以通过获取的过往观测数据来对卫星未来的过顶时间进行准确预测.而对于战时地面运动单位躲避卫星的问题,可以根据所面对的不同侦查卫星通过设置一个固定的路线,让地面单位在该路线中有计划的行驶,能够躲避多种卫星的侦查.
In order to avoid the detection of hostile military satellites during the war, it is necessary to make early warnings on the overdue time of the satellites, and to accurately predict the number of satellites whose parameters are to be disclosed, and to propose a basis for satellites with unknown parameters Past observation data to predict the satellite over-time train of thought: the satellite and the Earth’s complex three-dimensional coupling movement dimensionality reduction, and the ground as the reference system and found that satellite satellite movement trajectory has a high degree of periodicity, according to According to this idea, the past observation data obtained can accurately predict the overcapacity of the satellite in the future, while for wartime ground motion units, the problem of avoiding the satellite can be solved by setting up a fixed route according to the different detecting satellites , So that the ground units in the route of planned travel, to avoid the detection of a variety of satellites.
