Maintenance of Halo Orbits Under the Thrusting Constraints

摘要

This paper investigates the preliminary orbit maintenance for the next-generation infrared astronomical mission, Space Infrared Telescope for Cosmology and Astrophysics, which is to be launched into the sun-Earth L2 halo orbit Particularly, the impact of the reaction wheel unloading A V on the spacecraft trajectory from the viewpoint of orbit maintenance is analyzed. In addition, the nondivergent and suppressive methods using the characteristics of the dynamical theory for unloading △ V are proposed and validated.
