Problems solved by technology

[0006] The above scheme has the advantages of preventing the antenna from being wound due to the unlimited rotation of the antenna, and the position is reliable, but there are still shortcomings: gears and other parts are needed. Compared with the traditional limit mechanism, although the strength is increased and the reliability Enhanced, but the cost will be relatively high; and the above scheme still does not solve the problems of the transmission mechanism not in time, the tracking speed is too slow, etc.

Abstract

The invention discloses a marine satellite antenna. The marine satellite antenna comprises an antenna outer cover with a base, and an antenna system positioned in the antenna outer cover; the marine satellite antenna is characterized in that the antenna system comprises a parabolic antenna arranged on the base and a control circuit arranged in the base; the parabolic antenna is mounted on the basethrough a mounting base; an azimuth-drive motor capable of controlling circumferential rotation of the mounting base is arranged on the mounting base; a pitching motor connected to the parabolic antenna and capable of controlling the parabolic antenna to perform pitching rotation is arranged on the mounting base; a feed source is arranged in the parabolic antenna; a polarized motor capable of controlling the feed source to rotate is arranged below the parabolic antenna; the azimuth-drive motor, the pitching motor and the polarized motor are all connected to the control circuit; and the control circuit comprises a central processing unit and a closed-loop control circuit connected to the central processing unit. The marine satellite antenna has the advantages of high response speed, in-time satellite tracking and the like.

Description

technical field [0001] The invention belongs to the technical field of electronic communication, in particular to a ship satellite antenna. Background technique [0002] The satellite antenna is often called the cauldron, which is a metal parabola that is responsible for reflecting the satellite signal into the feed and tuner at the focal point. The function of the satellite dish is to collect the weak signal transmitted by the satellite and remove the noise as much as possible. [0003] In the actual application of the shipborne satellite communication antenna, due to its mobile characteristics on the sea and the rolling of the antenna beam caused by the sway of the ship, when the antenna is tracking the linearly polarized satellite, the polarization direction of the antenna often deviates from the polarization direction of the transponder, resulting in Signal fading and severe cross-polarization interference. Therefore, the shipborne satellite communication antenna shoul...
