Embodiment Construction

[0024] combine figure 1 , 2 According to the measurement and control process 1 (satellite launching to the deployment of the hood) and measurement and control process 2 (after the hood is deployed and on-orbit operation), combined with the various working modes and attitude changes of the satellite, the requirements for the coverage area of ​​the measurement and control antenna are analyzed, and the measurement and control antenna is determined. Use policy and install location.

[0025] In the measurement and control process 1 (satellite launch to the deployment of the hood), the first group of measurement and control antennas is used for satellite measurement and control. This group of measurement and control antennas is installed at a fixed position of the satellite and at the bottom of the hood.

[0026] Before the hood is unfolded, the first group of measurement and control antennas can meet the requirements of the measurement and control coverage area; after the hood is ...

Abstract

The invention relates to a method for designing a measurement and control antenna for high-orbit remote sensing satellites. Antenna and the second set of measurement and control antennas of the second set of measurement and control antennas; after the satellite is launched, the first set of measurement and control antennas of the two sets of measurement and control antennas are used for communication, and after the hood is unfolded, it is switched to the second set of measurement and control antennas for communication. Using the secondary deployment of the measurement and control antenna and the on-orbit switching technology, the strategy of configuring two sets of measurement and control antennas to perform satellite measurement and control in different time periods is proposed for the first time on the satellite. , the problem that satellite-to-earth measurement and control cannot be carried out.

Description

technical field [0001] The invention relates to a method for designing a measurement and control antenna for a high-orbit remote sensing satellite, and belongs to the technical field of satellite design. Background technique [0002] High-orbit satellites arrive at fixed-point positions in orbit after undergoing processes such as launch, take-off, transfer orbit, quasi-normal orbit, and normal orbit. Throughout the process, the TT&C antenna is the link between the satellite and the ground TT&C station, and the measurable range of the TT&C antenna plays an important role in restricting the satellite-ground TT&C. High-orbit satellites generally rely on a set of measurement and control antennas to complete the entire process of measurement and control tasks. This group of measurement and control antennas is installed at a fixed position on the satellite and put into use from the launch tower until the end of the satellite's life. [0003] High-orbit remote sensing satellites i...
