Horizon-Dependent Tube MPC for Elliptical-Orbit Rendezvous Under Mass Uncertainty
Omer Burak Iskender, Keck-Voon Ling
A spacecraft closing on a target from three hundred kilometres to contact flies one guidance law across five orders of magnitude of range, and a controller that is provably safe at…

Reachability-Based Safe-Start Regions for Approach to a Tumbling Target with Rotating LOS Constraints
Omer Burak Iskender, Keck Voon Ling, Wee Seng Lim +1
This paper presents a closed-form test that decides, before the maneuver begins, whether a chaser can reach and hold station at the hold point of a tumbling, uncooperative target i…

Low-Thrust Trajectory Optimization for Cubesat Lunar Mission: HORYU-VI
Omer Burak Iskender, Keck Voon Ling, Mengu Cho +2
This paper presents a low-thrust trajectory optimization strategy to achieve a near-circular lunar orbit for a CubeSat injected into a lunar flyby trajectory. The 12U CubeSat HORYU…
