摘要

Attitude changing duration between tasks is a main restriction of the task scheduling for an agile imaging satellite. Its value is quite difficult to acquire while considering the rotation of the earth, the movement of the satellite on its orbit, the visible time windows to the tasks and the attribute of the satellite. Besides, the efficiency improvement of its obtaining method is also significant for it would repeatedly run for thousands of times and consume a lot of time during the scheduling. In order to solve the problem, a spacial kinematic model is established by analyzing the constraints. Based on the model, an improved method is given to acquire the attitude changing duration. Simulation results show the efficiency of our approach.
