| Summary: | In order to avoid the high cost and high risk of demonstration mission of rendezvous-docking technology, missions using
nanosatellites have recently been increasing. However, there are few successful mission cases due to many limitations of
nanosatellites like small size, power limitation, and limited performances of sensor, thruster, and controller. To improve
the probability of rendezvous-docking mission success using nanosatellite, a rendezvous-docking phase analysis tool for
nanosatellites is developed. The tool serves to analyze the relative position and attitude control of the chaser satellite at the
docking phase. In this tool, the Model Predictive Controller (MPC) is implemented as a controller, and Extended Kalman
Filter (EKF) is adopted as a filter for noise filtering. To verify the performance and effectiveness of the developed tool for
nanosatellites, simulation study was conducted. Consequently, we confirmed that this tool can be used for the analysis of
relative position and attitude control for nanosatellites in the rendezvous-docking phase. |
