Relative Motion Transformation for Ground Robotics Test Bed in Rendezvous/Docking Simulation

As missions utilizing multiple satellites become more prevalent, the significance of rendezvous and docking (RVD) technology has markedly increased compared to the previous focus on single-satellite missions. Developed RVD technology can be validated beforehand using robot-based ground test beds, effectively reducing risks and costs. However, predicting the movements of robots to simulate satellite motion and replicating orbital maneuvers in confined spaces can be challenging. Therefore, this paper aims to address these issues and enhance ground-based testing methodologies, including techniques such as transforming relative motion, minimizing satellite’s rotational motion, and trajectory planning for precise replication of satellite kinematics. These approaches seem to strengthen the technological foundations essential for successful space missions and are anticipated to drive innovative progress in future space exploration and satellite operations.
