国外低轨道卫星综述

Survey of Foreign Low Earth Orbit Satellites

由于地球低轨道更利于收集情报信息 ,大多被军事侦察卫星所占有。随着太空军事化趋势的日益增强 ,了解和认识当前的低轨道卫星较为必要。介绍了典型低轨道卫星的军事作用和运作机理 ,并给出了当前在轨低轨道卫星的技术参数。

The low earth orbit is mostly occupied by military reconnaissance satellites for it is convenient to collect intelligence information. With the enhancement of the space militarization, it is necessary to know the present low earth orbit satellites. Military function and operation mechanism of low earth orbit satellites are introduced, and technical parameters of low earth orbit satellites are provided. Finally,trend of its development is analysed.
