Study on Halo Orbit Design Under High Precision Model

Abstract

For the long-term operational mission of the Halo orbit space station at the Earth-Moon L2 point in the future,the Halo orbit design method under the high precision model is studied. Firstly,the transformation relationship between the circular restricted three body problem (CR3BP) barycentric centroid coordinate system and the high-precision model geocentric J2000 coordinate system is deduced in details,and the closed Halo orbit under CR3BP is converted to the geocentric J2000 coordinate system,the iteration initial value of the Halo orbit for the high-precision model is obtained. Secondly,the sequential quadratic program (SQP) is used to construct a multi-layer iterative scheme and the initial value is corrected layer by layer in a highprecision model. Finally,through the simulation test,the feasibility and effectiveness of the method described in the article are verified. The research results can provide reference for the design of the nominal orbit design scheme for the future libration points.
