Abstract

The invention discloses a satellite antenna polarized closed loop tracking method and a device. The satellite antenna polarized closed loop tracking method comprises steps performing angle loop closing on a pitch angle, an azimuth and a polarized angle of the satellite antenna, regulating the pitch angle, the azimuth and the polarized angle to a first preset angle, a second preset angle and a third preset angle, performing polarized stepping tracking on a beacon signal of a satellite according to a beacon signal frequency, converting the beacon signal to a DC level signal according to the regulated pitch angle, the azimuth and the polarized angle, and regulating the rotation direction and the rotation angle of the satellite antenna according to the change of the DC level signal. The invention adopts the polarized tracking principle identical to the pitching tracking mode to realize the tracking of the angle closed loop and then the tracking of the signal closed loop, reduces the double-direction interference problem of the reversed polarized signal and improves the communication quality.

Description

technical field [0001] The invention relates to the field of satellite communication, in particular to a satellite antenna polarization closed-loop tracking method and device. Background technique [0002] Most of the automatic satellite communication antenna products on the market currently use the method of automatically calculating the theoretical data of the polarization angle based on the latitude and longitude of the station and the orbital position of the target satellite, and the control system drives the polarization mechanism to rotate to the designated position according to the theoretical value. , some products may correct the theoretical angle of polarization according to the roll angle, but they all belong to the open-loop tracking method. [0003] The polarization closed-loop technology is to improve the polarization isolation of the satellite earth station's transmission, so as not to interfere with the user signal working on another polarization transponder....
