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 design method of a measurement and control antenna used for a high-orbit remote sensing satellite. A first measurement and control antenna group which consists of a first set of measurement and control antenna and a second set of measurement and control antenna is mounted at the bottom end of a light-shielding cover; a second measurement and control antenna group which consists of a first set of measurement and control antenna and a second set of measurement and control antenna is mounted at the top end of the light-shielding cover; after the satellite is launched, the first measurement and control antenna group with two sets of measurement and control antennas is adopted for communication, and after the light-shielding cover is unfolded, the second measurement and control antenna group with two sets of measurement and control antennas is switched for communication; and by virtue of a secondary unfolding and on-orbit switching technology of the measurement and control antennas, a satellite measurement and control strategy with two groups of measurement and control antennas in different time frames is proposed initially on the satellite, so that the problem that planet ground measurement and control cannot be performed caused by shielding of the satellite measurement and control antennas due to on-orbit unfolding of the light-shielding cover of the high-orbit remote sensing satellite can be solved.

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...
