A Fault Handling Scheme for Remote Guidance of Autonomous Quick Rendezvous and Docking

A phase modulation method for remote guidance faults in autonomous and quick rendezvous and docking is proposed. According to position and attitude navigation information, ground fault judgment instructions, various fault modes corresponding to different autonomous quick rendezvous and docking fault conditions are given. The chaser spacecraft is guided to the frozen orbit behind the target spacecraft by using the two impulses orbit change strategy for typical fault modes. After the fault is removed, new rendezvous and docking can be achieved by guidance from ground for one or two days according to the current phase angle.
