分析俄罗斯导弹预警卫星工作状态

Analyze the Working Status of Russian Missile Early Warning Satellite

关于国外军事装备的状态情况往往由于保密原因很难有确切的报道,通过各类消息情报的信息往往有所出入、互相矛盾。尤其是对于导弹预警卫星这样的反导预警装备,准确获知其状态就更加困难。利用美国NASA公布的空间目标数据库,首先检索出俄罗斯导弹预警卫星全寿命周期内的轨道数据,然后通过分析其轨道根数的变化,综合考虑卫星在轨道摄动作用下是否进行轨位保持对应的轨道参数变化特征,明确卫星是否还在进行轨位保持,进而明确其是否还处在轨道寿命周期内,最终确定其实际工作状态。

Accurate reports of the status of foreign military equipment are often difficult to obtain for reasons of confidentiality,the information that passes through all kinds of information intelligence often has contract each other.Especially for antimissile early-warning equipment such as missile early-warning satellite,it is more difficult to know status accurately.Released by nation aeronautics and administration (NASA) space target database,a Russian missile early-warning satellite orbital data within the whole life cycle is firsty retrieved,and then through the analysis of the change of the orbit data,whether under the consideration of satellite in orbit perturbation action for orbital keep corresponding orbit parameters variation characteristics,clear whether the satellite in orbit keeping,and then clear whether it is in the life cycle of the tract,finally clarify the actual working condition.
