【摘要】 日—地+月系统的三角平动点相对两个中心天体不变的几何构型使得它们可以作为某些特殊探测器的放置场所。尽管在圆型限制性三体问题下三角平动点附近的运动是稳定的,在探测器的实际运行过程中,由于其它天体的摄动,轨道控制仍是需要的。根据三角平动点的动力学特征对探测器定点在日—地+月系统的三角平动点附近的轨道保持问题作了相应的研究。更多还原

【Abstract】 The equilateral equilibrium points in the sun-earth+moon system have fixed configuration with respect to the two primaries.They can be used for some spacecrafts with special purposes.Although these points are stable in the Circular Restricted Three-Body Problem,spacecrafts need control due to various perturbations in the real gravitation model of the solar system.This paper made some theoretical studies concerning the station-keeping of a spacecraft around these points.更多还原
