Embodiment Construction

[0016] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0017] Such as figure 1 As shown, the system includes: satellite antenna 1, low noise frequency converter (Low Noise Block, LNB) 2, beacon receiver 3-1, DVB receiver 3-2, antenna controller 4, borrower 5, modem 6 , A / D sampler 7 , polarization sensor 8 , inclinometer 9 , GPS (Global Positioning System, Global Positioning System) receiver 10 . It should be noted that the beacon is a tracking signal on every satellite. Selecting the beacon receiver can make the system track the satellite reliably, and the DVB receiver is used to receive the DVB signal on the satellite. Generally, there are user’s tracking signals on the satellite. DVB signal. The DVB receiver can identify...

Abstract

The invention discloses a satellite antenna tracking system with multiple receivers, comprising a satellite antenna, a low noise frequency converter connected with the satellite antenna, an adapter connected with the low noise frequency converter, an antenna controller and n antenna tracking receivers, wherein each antenna tracking receiver is connected with the adapter, one end of the antenna controller is connected with the satellite antenna, the other end is respectively connected with each antenna tracking receiver, and the antenna controller is used for selecting one signal from n signals outputted from the n antenna tracking receivers as a reference signal and aligning the satellite antenna to a satellite through adjustment according to the reference signal. The system can increase the reliability of an antenna system in finding the satellite.

Description

technical field [0001] The invention relates to the technical field of automatic star-seeking satellite antennas, in particular to a multi-receiver satellite antenna tracking system. Background technique [0002] When the automatic satellite antenna is working, the traditional method is to configure a receiver (usually a DVB receiver) to receive the reference signal on the satellite, and the antenna tracking system automatically controls the alignment of the antenna according to the DC level intensity output by the receiver. satellite. Due to the instability of the satellite reference signal, the satellite antenna cannot correctly track the required working satellite. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the invention is: how to improve the reliability of the antenna system for finding stars. [0005] (2) Technical solutions [0006] In order to achieve the above object, the present invent...
