MISSION RESCHEDULING FOR GEO ACTIVE DEBRIS REMOVAL

In this paper, the rescheduling problem of debris removal in a coplanar GEO orbit is studied. The minimum-cost, two-impulse phasing maneuver is used for each rendezvous. Specifically, the SSc is conducting Active Debris Removal mission on schedule, and the remaining mission sequence is known. Suddenly, the users demand to insert new targets in emergency. A new mission sequence with new targets and un-completed targets is required. The goal of the rescheduling is to work out such a new scheme for the SSc, minimizing the total rendezvous cost, as well as designing the rendezvous trajectories. The reschedule model and solution algorithm are developed. Numerical simulations are carried out to demonstrate the effectiveness of the model and rescheduling method.
