DOI: 10.1016/j.ifacol.2018.07.101
Abstract: Abstract We study the problem of spacecraft rendezvous and docking, specifically the tradeoff between safety and efficiency. The safety component in this problem is to stay within a line-of-sight cone and reach the target at… read more here.

DOI: 10.1109/tcst.2022.3216077
Abstract: We develop a spacecraft rendezvous policy that ensures safe, collision-free trajectories under various thrust failure scenarios. We use backward reachable sets (RSs) to characterize the unsafe region where, if a failure occurs, a collision between… read more here.
