Horizon-Dependent Tube MPC for Spacecraft Rendezvous on Elliptical Orbits with Conditional Robust Constraint Satisfaction
Omer Burak Iskender
Spacecraft rendezvous on elliptical orbits must hold a safety corridor under navigation noise, unmodelled perturbations, and thrust errors driven by propellant mass uncertainty. Th…
Drift-Aware Multi-Target Space Tug Logistics Using Natural Orbital Precession
Omer Burak Iskender, Leonard Felicetti, Kaan Gokturk +2
Multi-rendezvous missions for active debris removal and in-orbit servicing incur prohibitive propellant costs when their targets differ in the orientation of their orbital planes,…
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 reachability-aware guidance architecture for autonomous approach to a tumbling, uncooperative target under a rotating line-of-sight (LOS) docking corridor. Th…
Integrated Lander-Propulsion-GNC Framework for Autonomous Lunar Powered Descent
Emre Aklan, Fatih Seker, Bekir Gencalioglu +5
This paper presents an integrated lander-propulsion-GNC framework for autonomous lunar powered descent. The BUG VTVL test vehicle serves as the reference platform, with the YUNT V0…
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…
