太阳同步卫星的轨道设计

Orbit Design of Sun-Synchronous Satellite

在轨道六要素的基础上,分析了卫星太阳同步轨道设计时降(升)交点地方时、升交点赤经,以及冻结轨道参数等的确定方法。并给出了在轨道交点周期、回归圈数、回归周期、重复周期和其他因素等约束条件下的轨道设计要点。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。

The determination method of descending/ascending node, longitude of ascending node and frozen orbit parameters for sun-synchronous orbit satellite design was analyzed on the basis of six general orbital elements. The key points of the design under the restrained conditions, such as orbit node period, regressive cycles, regressive period, repeat period and others, were also presented. 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.
