Abstract

The invention discloses a multi-band UV measurement and control system. The system comprises an antenna system, a feed source system, a channel grid switching system, a receiving channel, a transmitting channel and the like. The antenna system is composed of four UV antennas with different frequency bands. UV wide-band coverage is realized, left-handed and right-handed circular polarization switching of the feed source system is realized, transceiving signal switching of different antennas and different polarization networks is realized by the channel system, and the problems of narrow band coverage, single received signal and difficulty in wide-band measurement and control networking of multiple measurement and control stations of a current measurement and control ground station are solved. On the basis of reducing the size of a measurement and control station, improving the system performance, reducing the cost and improving the reliability, the multi-band UV measurement and controlsystem provided by the invention has the advantages of wide band coverage, strong signal adaptability, high reliability, low cost and the like through loop iteration of long-time test.

Description

technical field [0001] The invention belongs to the field of satellite communication, is especially suitable for commercial satellite measurement and control, and is a measurement and control ground station system supporting UV multi-band and multi-polarization signal transmission and reception. Background technique [0002] In recent years, with the rapid development of commercial aerospace applications, the mass production technology of cube satellites and other standardized satellites has become increasingly mature, the deployment of satellite constellation systems has increased, and the number of satellites in orbit has increased significantly. The advent also brought about a shift in the development of satellite technology. As a key link to ensure the normal operation of satellites in orbit, satellite measurement and control plays an increasingly important role in the entire commercial aerospace industry chain. [0003] As the number of satellites continues to increase...
