摘要
本文首先说明太空任务与轨道设计的关系 ,接着介绍轨道的基本性质。从地球重力势的观点看各种常用的绕地轨道 ,包括地球和太阳同步轨道及Molniya轨道。从扰动的观点看常用的星际轨道 ,包括LISA、ASTROD、SOHO轨道。最后对星际轨道设计 ,说明二点边界值问题的数值解法、飞掠星体的应用、最佳化的考虑 ,并用以设计 2 0 1 5年发射的ASTROD初步任务轨道。
In this paper we first describe the relations between space mission and orbit design, and then introduce the basic properties of the orbit. Geopotential representation is used to illustrate the common used Earth orbits, including Sun-synchronous orbits and Molniya orbits. Perturbation concept is used to demonstrate the mission orbits of LISA, ASTROD, and SOHO. Finally, for the interplanetary orbit design, the numerical methods of two-point boundary-value problems, the applications of fly-past, and the considerations of optimization are discussed, and are utilized to preliminarily design the mission orbit of ASTROD spacecraft to be launched in 2015.
