Problems solved by technology

At present, the method of determining the installation position of the antenna is mainly based on the antenna directional gain line diagram. The installation position of the antenna is mainly selected manually. There is no mature and fixed selection standard, and there is no fully automated selection method.

Embodiment Construction

[0039] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0040] In order to solve the above technical problems, the present invention provides a method for determining the installation position of the spacecraft antenna and the selection of the antenna pointing, such as Picture 1-1 , Figure 1-2 and figure 2 As shown, the method is based on the antenna installation angle α and β and the four-dimensional discrete traversal search method of the azimuth angle Az and the elevation angle El in the antenna coordinate system to calculate the antenna installation position and antenna pointing;

[0041] The method comprises the steps of:

[0042] Step S1: Set the spacecraft orbit, antenna pattern, station 1, station 2... to station N station layout and measurement and control comm...

Abstract

The invention belongs to the technical field of spacecraft flight measurement and control, and particularly relates to a spacecraft antenna installation position and antenna direction selection determination method. The method comprises a setting link, a geometric visible arc section operation link, an antenna installation angle traversal range operation link, a first judgment link, an intersection range operation link, a link margin operation link, a second judgment link, a third judgment link, a result operation link and a result output link. Compared with the prior art, according to the selected spacecraft orbit data, the antenna pattern, the measurement and control station layout and the spacecraft and ground equipment measurement and control communication link constraint, the antenna installation position and the antenna direction meeting the measurement and control task requirement are automatically calculated, and automatic design of the spacecraft antenna installation position and the antenna direction is achieved.

Description

technical field [0001] The invention belongs to the technical field of spacecraft flight measurement and control, and in particular relates to a method for determining the installation position of a spacecraft antenna and selecting the antenna pointing. Background technique [0002] In spacecraft flight measurement and control missions, the antenna installation position of the spacecraft is an important constraint factor in mission design. During the flight of the spacecraft, the distance and azimuth angle of the radar of the ground measurement and control station and the sea survey ship relative to the spacecraft are constantly changing, while the antenna on the spacecraft is installed at a fixed position relative to the spacecraft. The installation position of the antenna on the spacecraft must meet the requirements of measurement and control coverage. At present, the method of determining the antenna installation location is mainly based on the antenna directional gain l...
