嫦娥二号在国际上首次成功实现了从月球环绕轨道飞向日-地拉格朗日L2点的飞行任务.本文系统地研究了该任务的轨道设计问题,提出了高精度星历模型下日-地拉格朗日L2点附近Lissajous目标轨道的设计方案;针对复杂日-地-月系统动力学环境,基于非线性动力系统流形等理论,提出了日-地与地-月双三体系统下的低能量转移轨道方案.飞行试验结果证明了嫦娥二号日-地拉格朗日L2点探测轨道设计方案的正确性和可行性.
For the first time in the world, Chang’e II successfully achieved its mission of flying from the lunar orbit to Day-Lagrangian L2. This paper systematically studies the orbital design problem of this task and proposes that the high-precision ephemeris model - Design scheme of Lissajous target orbit around L2 point in Lagrange; According to the theory of complex dynamical environment of day-earth-moon system and non-linear dynamical system manifold, System under the low energy transfer orbit scheme.The flight test results prove the correctness and feasibility of the design scheme of Chang’e II Lagrange L2 exploration orbit.
