The Method of Medium-Low Altitude Satellite Control

中低轨道卫星控制方法

With the growing use of the geostationary orbit, the increasing geostationary satellite has led to congestion at hot spots in the geostationary altitude in particular.

随着各国对地球静止轨道的利用，静止轨道卫星的数量急剧增加，造成了静止轨道局部特别是热点地区较为拥挤的现象。

Remote sensing image is the electromagnetic radiation record of surface features' high altitude satellite observation, two-dimensional projection of surface features 'Three-Dimension info and comprehensive Description of surface features' spectrum, space and time info.

遥感数字影像是通过卫星高空拍摄地物电磁辐射记录，是地物三维信息的二维投影，是地物的波谱信息、空间信息和时间信息的综合描述。

As a movable target simulator, the double-cone type IR earth sensor can be conveniently applied to stationary linearity testing and altitude-control system testing of airship and satellite after general assembly on launching position.

作为双圆锥式红外地球敏感器的可动目标模拟器，能方便的用于飞船和卫星总装以后及发射阵地的红外地球敏感器静态线性度测试和姿控系统测试。

At last, an example of design for sun-synchronous, frozen and return orbit in the orbit of some satellite which altitude was 750 to 800 km was given.

最后给出了一个轨道高度750～800km，卫星太阳同步轨道、冻结轨道和回归轨道的算例。
