Abstract

The invention belongs to the technical field of spacecraft flight measurement and control, and relates to a spacecraft antenna installation position and antenna direction selection determining system. The system comprises a setting module, a geometric visible segmental arc operation module, an antenna mounting angle traversal range operation module, a first judgment module, an intersection range operation module, a link margin operation module, a second judgment module, a third judgment module, a result operation module and a result output module. According to the system of the invention, on the basis of selected spacecraft orbit data, antenna patterns, 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 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 system for determining the installation position of a spacecraft antenna and selecting the antenna direction. 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 ...
