在定点发射条件下,针对中国目标区域的典型任务,研究了快速响应太阳同步轨道及发射窗口的一体规划方法。基于固定的火箭飞行地心角和飞行时间,根据发射点和目标点位置关系,通过球面几何原理,提出了快速响应太阳同步轨道及发射窗口的解析规划方法。针对具体任务,得到了快速响应太阳同步轨道和发射窗口的规划结果,并通过STK仿真进行了验证,证明了规划方法的可行性、实用性,对空间快速响应轨道规划具有借鉴意义。

Under the condition of fixed launch point,an integrated design method of operationally responsive sun-synchronous orbit and launch time is studied for the typical mission of target point in China. Based on the constant geocentric angle and time of launch vehicle flight,an analytical method of operationally responsive sun-synchronous orbit and launch time is proposed by spherical geometry due to the relative position between launch point and target point. For a specific mission,the operationally responsive sun-synchronous orbit and launch time are obtained by the analytical method and verified by STK simulation in order to prove the feasibility and practicability of the method. The results can serve as reference for the orbit design of operationally responsive space.
