标题： Long-Term Earth Magnetosphere Science Orbit via Earth-Moon Resonance Orbit

摘要： 本文研究地球磁层内的长期轨道，特别关注那些近日点幅角与月球引力辅助引起的改变以及地球纬度幅角在地月共振完整轨道周期内同步的轨道。 在地月旋转参考系中，共振轨道表现出重复性；然而，由于月球飞越的第三体效应，近日点幅角会发生变化。 这种变化的程度受与共振轨道相关的雅可比积分影响。 为了确定可行的共振轨道和最优雅可比积分，我们为每个潜在轨道绘制近日点幅角变化与雅可比积分的关系图。 这种同步使得从日地旋转参考系观察时，航天器能够保持在空间的一个受限区域内。 最后，本文讨论了这些长期地球磁层科学轨道的应用，包括轨道定向重新配置（保持位置）和稳定性。 显示英文摘要

摘要： This article investigates long-term orbits within the Earth's magnetosphere, specifically focusing on orbits where the argument of periapsis is synchronized with changes induced by lunar gravity assists and the Earth's argument of latitude over a complete orbital period in Earth-Moon resonance. In the Earth-Moon rotating frame, resonance orbits appear repetitive; however, the argument of periapsis shifts due to the third-body effects from lunar flybys. The extent of this shift is influenced by the Jacobi integral associated with the resonance orbit. To identify feasible resonance orbits and the optimal Jacobi integral, we map the argument of periapsis change against the Jacobi integral for each prospective orbit. This synchronization allows the spacecraft to remain within a confined region in space when observed from the Sun-Earth rotating frame. Finally, the article discusses the applications of these long-term Earth magnetosphere science orbits, including orbit-orientation reconfiguration (station keeping) and stability.
