Design method of high-reliability ground measurement and control link in electrical test of satellite launching region

Abstract

The invention provides a design method of a high-reliability ground measurement and control link in an electrical test of a satellite launching region. The method includes following steps: step 1, two pairs of ground measurement and control antennas are erected on a tower fixing platform, uplink and downlink shunting are performed through a plurality of circulators, the two pairs of ground measurement and control antennas are respectively connected to a main interface and a backup interface of a base RF fiber repeating system, and when the ground measurement and control antennas of the main interface are shielded or not stable, base personnel directly switches to the backup antennas through a switch matrix of the fiber repeating system. According to the method, conventional equipment resources can be fully utilized, the redundant heat backup design of the ground measurement and control link is performed, and the troubleshooting time is reduced as much as possible.

Description

technical field [0001] The invention relates to a link design method, in particular to a design method of a high-reliability ground measurement and control link for electrical testing in a satellite launch area. Background technique [0002] When the satellite is electrically tested in the launch area of ​​the launch site, it has high requirements for the reliability of the ground telemetry and remote control link, especially after entering the launch process before launch, once the telemetry and remote control link is abnormal, it may cause delays in launch. [0003] At present, the ground measurement and control link scheme commonly used in plant testing requires full-link testing, so the backup equipment or channels are limited, resulting in some single points on the link. For example, the management equipment of the measurement and control center is the key equipment for remote control and telemetry data processing. Generally, a cold backup solution is adopted, and only ...

[0002] When the satellite is electrically tested in the launch area of ​​the launch site, it has high requirements for the reliability of the ground telemetry and remote control link, especially after entering the launch process before launch, once the telemetry and remote control link is abnormal, it may cause the launch to be delayed

[0003] At present, the ground measurement and control link scheme commonly used in plant testing requires full-link testing, so the backup equipment or channels are limited, resulting in some single points on the link. For example, the management equipment of the measurement and control center is the key equipment for remote control and telemetry data processing. , a cold backup solution is generally adopted, and only one of the test systems is in working condition. Once a problem occurs, the primary device needs to be removed and the backup device replaced. During the replacement period, the entire satellite telemetry monitoring cannot be performed, and remote control commands cannot be sent to the satellite.

However, after entering the launch site, especially when entering the launch area, the general measurement and control link only needs to ensure that one path is absolutely reliable, and there are redundant channels for radio frequency links or equipment. Therefore, in order to improve the reliability of the ground measurement and control link, make full use of It is an inevitable requirement to re-optimize the link design of resources
