Orbit Maneuver Scheme Planning For Rendezvous Of High-orbit Targets

This paper systematically analysis the orbital maneuver strategy of high target orbit rendezvous mission on each flight phase. The flight path about the high target orbit rendezvous mission can be generally divided into two categories: One is the coast flight phase. The time of this flight phase occupies most of the rendezvous mission. The second category is the powered flight phase, required by active control during the stage and the orbital flight path will set by the implementation of pre-mission. The second flight phase is the focus of this paper.For coast flight phase, the orbital dynamics simulation is without active control only to consider the impact of perturbation. The orbital flight phase, while not controlling, but in practical engineering, orbital perturbations can not be neglected. Especially for high-orbit rendezvous mission, the coast flight phase has a long flight time and it is sensitive to the perturbation, which will greatly impact the orbital control strategy of the powered flight phase which is between the coast flight phases. Therefore, to the orbit maneuver planning strategy in this study, the coast flight phase is closely related to the orbital control strategies during the coast flight phase.For powered flight phase of the orbit maneuver, in this paper, the common strategy is to get guidance impulse and perform it by use of finite thrust strategy. So this strategy will be divided into impulse strategy and finite thrust strategy. Impulse strategy is based on the whole process of high-orbit targets rendezvous mission, and the optimization of fuel consumption is considered in this issue. For the finite thrust strategy, its objective is to promote the orbit controlled by the finite thrust approach to the nominal target orbit which is obtained by the impulse. The main consideration is the orbital control precision of orbit maneuver.Finally, through the whole orbital dynamics simulation, based on the high target orbit rendezvous mission, the verification of the orbital maneuver strategy is feasible.
