长周期高精度回归轨道与脉冲轨道控制策略设计

Aimed at the design and maintenance of long-duration repeat ground-track orbit, this paper deals with a semi-analytical method based on high-order Poincaré maps for the optimal design and control of repeat ground-track orbit in the high-precision gravity fields, including the factors of atmospheric drag, solar radiation pressure and three-body perturbations. The method is based on the high-order expansion of Poincaré maps, which is expressed as the polynomials, to propagate the orbit for one or more repeat cycles, enabling the precise orbit design and control by performing impulsive control at the equatorial crossings. The method, aimed at both the high-accuracy and low-accuracy constraints, is proposed and applied to missions like the repeat pattern of TerraSAR-X, Landsat-8, IRS-P6, SPOT-7 and UoSAT-12. The present method has the advantages in high computational efficiency and high accuracy, which is suitable for the on-board autonomous orbital propagation and orbital control.
