Abstract

Space laser communication has the advantages of fast transmission rate, strong anti-interference ability and high confidentiality, and is the future development trend of high-speed data transmission in space. The laser beam dispersion angle is small, and the field of view of space environment reception is limited, so it is necessary to track the beam stably in order to realize high-speed data communication. However, due to the influence of certain environmental factors or internal factors of the terminal, the tracking process will inevitably break the chain, which can not ensure stable data communication. Acquisition and tracking is a fast servo control system. It is difficult to diagnose the cause of chain breakage by viewing the telemetry on the bus to capture the state at the moment of chain breakage after the chain is built by on-rail laser communication. Aiming at this problem, this paper proposes a diagnostic method of broken chain for space laser communication, so that the relevant data can be locked at the moment of broken chain after the satellite enters the orbit and the data can be transmitted back to the ground. Then the professionals can analyze the cause of the broken chain and find the corresponding solutions to modify it in the orbit.
