摘要
针对常比冲与变比冲两种推力模型下的对地多目标的观测任务作了初始轨道设计。航天器平时处于待命轨道正常运行,接到观测命令后,作轨道机动,依次通过所关心的多个目标上空。根据问题描述,利用勒让德伪谱方法,给出常比冲与变比冲推力下,对地多目标观测的设计方法。最后以3个目标为例,分别设计了常比冲与变比冲推力下的多目标观测轨道。
Initial orbit design for multiple surface targets observation with constant and variable specific impulse is given. The space vehicle starts maneuvering from its stand-by orbit after receiving the observation order and its ground track passes the designated targets as soon as possible. According to the problem description, with Legendre Pseudospectral method applied, orbit design method for multiple targets observation with constant and variable specific impulse is given followed by a three-target example.
