Generalised multi-impulsive manoeuvres for optimum spacecraft rendezvous in near-circular orbit

摘要

This work describes the design of an impulsive manoeuvres’ planner\udmeant for onboard autonomous optimum formation flying reconfigurations in near-circular orbit. The whole variation of the relative orbit is stepwise\udachieved through intermediate configurations, so that passive safety and delta-v consumption minimisation are pursued. The description of the relative motion is accomplished in terms of relative orbital elements and the reconfiguration plan takes into account mean effects due to the Earth oblateness coefficient and differential drag. Manoeuvres consist of sets of triple tangential impulses and a single out-of-plane burn to establish each intermediate configuration. They are scheduled in time intervals compliant with the user-defined permissible time control windows.
