High circular polar orbits around the Moon are considered as one of the options for placing a prospective lunar station. Due to gravitational perturbations from the Earth, such orbits are subject to the Lidov–Kozai effect. This effect results in the increase in the average value of the eccentricity, which eventually leads to the collision of the spacecraft with the lunar surface. Therefore, when used in lunar missions, these orbits require periodic corrections. The work proposes a station-keeping technique for high near-circular polar lunar orbits based on the dynamical structures of the double-averaged equations of motion that include the central gravitational fields of the Earth and the Moon. The annual station-keeping delta-v for a 10,000 km polar orbit is presented considering navigation errors and maneuver execution errors. The nominal parameters of the orbit are selected to increase its lifetime.

在环绕月球的近圆形高极轨道上保持站位

环绕月球的高圆极轨道被认为是放置未来月球站的选择之一。由于来自地球的引力扰动,这样的轨道会受到 Lidov-Kozai 效应的影响。这种效应导致偏心率平均值增加,最终导致航天器与月球表面发生碰撞。因此,当用于月球任务时,这些轨道需要定期修正。这项工作基于包括地球和月球中心引力场的双平均运动方程的动力学结构,提出了一种用于高近圆极地月球轨道的站位保持技术。考虑到导航误差和机动执行误差,提出了 10,000 公里极地轨道的年度站位保持 delta-v。
