Autonomous proximation operation with a space non-cooperative target have attracted widespread attention from various countries and organizations around the world, such as space debris removal, failed satellite maintenance, and so on. To fulfill these missions successfully, the following basic tasks should be carried out: (1) no collisions occur between the service spacecraft and the target during the final proximity process, which is viewed as the precondition of all the subsequent operations. (2) High precision position tracking and velocity synchronization are the basis of the approaching mission, ie, the chaser should reach the desired position and track the rotation and translation motion of the target. (3) To reduce the problem of communication delay and data loss, the communication ability of the spacecraft is considered. A spherical communication boundary is introduced to restrict the maximum distance between the chaser and the target. To tackle the accomplishment of these basic tasks, this paper proposes a tasks-priority-based collaborative guidance scheme, which can avoid conflict among different tasks during the whole proximity operations. Finally, simulation scenarios are performed to testify the effectiveness of the proposed control approach. The results show that the proposed guidance scheme can enable the service spacecraft to approaching mission while complying with the forbidden zone strictly.
