Abstract

The embodiment of the application discloses a disaster recovery backup method and system for a satellite control center of a low-earth-orbit satellite ground measurement and control system. At least one backup satellite control center is arranged in a main satellite control center; the main satellite control center and the backup satellite control center are geographically located in different areas and are provided with different power supplies; the states of the main satellite control center and the backup satellite control center are mutually exclusive; and one and only one main satellite control center exists at the same moment. Therefore, the complete division of management and information processing of the main satellite control center and the backup satellite control center is realized; remote measurement, remote control, distance measurement, speed measurement and interactive communication of external interface information are carried out between the main satellite control center and the backup satellite control center; the complete backup of the core information of the main satellite control center by the backup satellite control center is realized; and when the main satellite control center fails, real-time seamless switching can be realized. The disaster recovery backup method and system are suitable for the design and construction of disaster recovery backup of thesatellite control center of the low-earth-orbit satellite ground measurement and control system, so that the reliability and availability of the ground measurement and control system are improved.

Description

technical field [0001] The invention relates to a disaster recovery and backup method and system for a satellite control center of a low-orbit satellite ground measurement and control system. Background technique [0002] The near-Earth satellite ground measurement and control system includes a satellite control center and a measurement and control station, generally consisting of a satellite control center and multiple measurement and control stations. [0003] The satellite control center is mainly responsible for back-end data processing, including telemetry data processing, satellite status monitoring, remote control instruction or data block processing, positioning data downloaded by telemetry and ground ranging and speed measurement data orbit determination, etc.; Interactive channels, tracking satellites, and completing the conversion of digital signals and radio frequency signals. [0004] For the near-Earth satellite ground TT&C system, in order to ensure the relia...
