摘要

由于太阳同步回归轨道既可以满足光照条件的要求，又可以满足时间分辨力的要求，所以成为对地观测航天器首选轨道之一。由于Q值是将太阳同步轨道和回归轨道联系起来的桥梁，所以Q值在设计太阳同步回归轨道中起着举足轻重的作用，是太阳同步回归轨道设计时最先考虑的参数。通过对太阳同步轨道和回归轨道特性的分析，可以建立Q值与太阳同步回归轨道参数之间的数学关系，此关系是设计太阳同步回归轨道的依据。通过对轨道回归特性的分析，引入了设计太阳同步回归轨道Q值的方法。最后，结合某航天任务的具体指标，利用Q值选取算法，设计了一条满足实际航天任务需求的太阳同步回归轨道。基于Q值选取的轨道设计算法从理论上找到了太阳同步轨道设计中的关键，为复杂的轨道设计工作提供了一个可靠而易行的方法。

Abstract

Repeat sun-synchronous orbit is one of the most frequently used orbits for earth observation missions

because the orbit can satisfy the requirement of illumination and temporal resolution. Q value is the connection between sun-synchronous orbit and repeat orbit

so Q value

which is one of the first considerable parameters in the design of repeat sun-synchronous orbit

plays an important role of repeat sun-synchronous orbit design. First of all

the characteristics of sun-synchronous orbit and repeat orbit are analyzed

and the relationship of Q value and repeat sun-synchronous orbit is established

according as which repeat sun-synchronous orbit can be designed. Second

with the analysis of repeat orbit characteristics

derive a Q value design method of repeat sun-synchronous orbit. In the end

it is presented how to design a repeat sun-synchronous orbit satisfying mission requirements with an example. The method finds the key point of repeat sun-synchronous orbit design in theory

and provides a credible and easy method for complex orbit design tasks.
