摘　　要：基于圆形限制性三体问题下地月平动点的3阶轨道解析解,分析不同初值条件下的轨道演化特性,并基于误差传播理论研究地月历表误差对地月共线平动点周期轨道在不同初值及初值误差时的影响。结果表明:1)轨道误差与地月历表误差在同一个量级,当地月历表误差均值不为0时,其峰值大约为地月历表误差的2.5倍,轨道误差随时间变化的无量纲周期约为轨道无量纲周期的0.5倍;2)在同一条轨道的不同位置,地月历表误差影响存在较大差异,平面Lyapunov轨道、Halo轨道和垂直Lyapunov轨道误差的峰值点分别位于或接近X向最大值与最小值处、Z向最大值与最小值处和z=0处。Based on the third-order analytic solution of orbit of circular restricted three-body problem,we analyze the orbital evolution character under different initial conditions.Based on the theory of error propagation,we examine the influence of cislunar ephemerides error on the circular collinear libration points orbits at different initial values and initial errors.The results show that:1)The orbit error is in the same order of magnitude as the cislunar ephemerides error,and its peak value is about 2.5 times the cislunar ephemerides error when the mean value of the cislunar ephemerides is not zero,and the dimensionless period of orbit error is about half of that of the orbit.2)There are great differences in the influence of cislunar ephemerides error at different positions of the same orbit.The error peak points of plane Lyapunov orbit,Halo orbit and vertical Lyapunov orbit are at or near the maximum and minimum values in X direction,at the maximum and minimum values in Z direction and z=0,respectively.
