Abstract A brief introduction to the meaning of on-orbit services and research on space-based services is provided in this work. In the context of on-orbit service, the near-circular orbit is idealized as a disturbed circular orbit, and a general equation for the optimal maneuver of the near-circle orbit is presented. The examples of coplanar on-orbit services in low, medium and high orbits are analyzed respectively, and the best maneuvering scheme for orbit transfer is solved by special software. Further analysis of the impact of different heights of parking orbit on the optimal maneuvering scheme reveals that the closer parking orbit to the target orbit, the less energy is required for maneuvering, but the phase-modulation time and the transport capacity of the launch vehicle should be considered comprehensively.
Abstract The concept of on-orbit service is introduced, and the development process of on-orbit service is briefly reviewed. The optimal transfer plan of orbit transfer and rendezvous is studied in the context of on-orbit service. The circular orbit motion with perturbation is used to study the near-circle orbit maneuver, and the general equation of coplanar maneuver is established based on the cylindrical coordinate system. The influences of the orbital parameters and the difference initial phase between the coaxial orbits on the optimal transfer orbit are calculated by Matlab simulation.
