Navigation and Control Scheme for Space Rendezvous and Docking With Maneuvering Noncooperative Target Based on Dynamic Compensation

Abstract

Rendezvous and docking with noncooperative targets is one of the key technologies for on-orbit service such as satellite maintenance, space supply and space debris cleaning, etc. For the rendezvous and docking with maneuvering noncooperative targets, a relative measurement scheme based on one monocular camera and one distance sensor is designed. A dynamic compensation filter (DCF) is also proposed to estimate the relative state and the unknow maneuver of the noncooperative target. Meanwhile, the control scheme to fulfill the rendezvous and docking mission is given. Compared with the extended Kalman filter (EKF) and variable state dimension estimator (VSDE), the numerical simulation results demonstrate that the proposed estimator has better performance in estimating the relative state and target maneuver. The control scheme based on DCF can accomplish the rendezvous and docking task when the noncooperative target performs time-varying maneuvers.
