Design of data communication system for space manipulator teleoperation

The teleoperation of space manipulator is an important part of the operation of the space manipulator. In this paper, the main working mode of the manned spacecraft manipulator used for on-orbit servicing is introduced, the data communication system for the on-orbit operation and teleoperation mode is designed. Based on CCSDS AOS, the space-ground communication protocol for teleoperation is designed, in the application layer, the strategy of the instruction sequence buffering in sending and receiving end is adopted to solve the influence of the delay jitter on the stability of the manipulator control, the time synchronization problem of the virtual predictive operation model is solved by using the sequence count stamp method. In the end, the time delay composition and time characteristics of a typical remote operation task are analyzed.
