Trajectory Planning for Spacecraft Rendezvous in Elliptical Orbits with On / Off Thrusters
(Elsevier, 2014)
In a previous work, the authors developed a trajectory planning algorithm for spacecraft rendezvous which computed optimal Pulse-Width Modulated (PWM) control signals, assuming that the target was moving in a circular ...

A Flatness-Based Trajectory Planning Algorithm for Rendezvous of Single-Thruster Spacecraft
(Elsevier, 2018)
This work presents a trajectory planning algorithm for spacecraft rendezvous with a passive target. The main assumption is that the chaser vehicle has a single thruster and an attitude control system (e.g. reaction wheels) ...

A Predictive Guidance Algorithm for Autonomous Asteroid Soft Landing
(Elsevier, 2018)
The objective of this work is to present a closed-loop guidance algorithm for landing a probe on an irregular shaped rotating asteroid. The main assumption is that the spacecraft is orbiting close to the asteroid and has ...

Trajectory Planning for Spacecraft Rendezvous with On / Off Thrusters
(Elsevier, 2011)
The objective of this work is to present a trajectory planning algorithm for spacecraft rendezvous that is able to incorporate Pulse-Width Modulated (PWM) control signals. The algorithm is based on linearization around a ...
