Abstract

The invention provides a method for realizing a pointing attitude of a quantum satellite to a ground optical station. A scientific application system formulates a scientific experiment plan, includingground optical station configuration, ground optical station geographic coordinates and other parameters participating in the scientific experiment as well as exit-entry moment forecast data of the ground optical station involved in the quantum satellite transit scientific experiment plan. The quantum satellite comprises a satellite platform, and the satellite platform bears optical loads such asa secret key communication machine, an entanglement source and an entanglement transmitter. The satellite-to-ground optical station pointing top pouring attitude guidance law comprises a first attitude guidance law and a second attitude guidance law, and the satellite-to-ground optical station pointing top pouring attitude guidance law is formed after the second attitude guidance law is seamlessly combined and then the first attitude guidance law is seamlessly combined. Through the strategy of satellite platform in-orbit yawing attitude maneuver, a problem that a quantum satellite optical device keeps a polarization state with a specific requirement in a quantum satellite scientific experiment can be solved.

Description

Technical field [0001] The invention relates to the technical field of quantum satellites, in particular to a method for realizing the pointing posture of a quantum satellite to a ground optical station. Background technique [0002] Quantum science experiment satellites require satellite platforms to point to specific ground optical stations during satellite-to-earth quantum communication experiments. On this basis, the payload uses its own rotating mechanism and algorithms to complete high-precision ground stations within a limited range of maneuvers. Pointing to ensure effective satellite-to-ground communication by quantum science experimental satellites. Quantum communication uses quantum polarization states to carry information, and ground optical stations and quantum satellites share the same reference frame to compare quantum polarization states to achieve quantum communication. During the on-orbit test of the quantum satellite payload, if the polarization characteristics...
