Abstract: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.
