title = "Optimized collision avoidance of spacecraft in ultra close proximity for failed satellite",
abstract = "In this paper, a trajectory planning algorithm for optimized collision avoidance is presented regarding a chasing spacecraft. The spacecraft is supposed to operate in the ultra-close proximity around a failed satellite. The complex configuration and tumbling motion of the failed satellite are considered. Two-spacecraft rendezvous dynamics is formulated in the target body frame, while collision avoidance constraints are detailed, especially concerning the position uncertainties. An error ellipsoid is particularly involved corresponding to the uncertainties. An optimization solution of the approaching problem is generated with the Gauss Pseudospectral method, and modified in a close loop control. Numerical results are given to demonstrate the effectiveness of the proposed algorithms.",
