- Abstract
Relative attitude and position determination and control with a cooperative target in proximity operation is a critical technology in autonomous rendezvous and docking, which is necessary for the ISS logistic resupply. In proximity operation, the relative attitude and position are seriously coupled, due to the complex dynamics. To solve this problem, a novel approach to synchronously determine and control the relative attitude and position is proposed. The optical instrument fixed on the chase spacecraft obtains the image information from the beacons installed on the target. Based on the relative attitude and orbit dynamics and control laws, using the image information and gyro measurement, extended Kalman filter (EKF) is designed to estimate all the dynamic states in a closed loop dynamics. Taking the estimate of relative states as the input of the relative control laws, we achieve synchronous control to the relative attitude and position. Finally, simulation results of this approach show that the method is feasible and effective for the relative attitude and orbit control problem with a cooperative target in proximity operation.
