A follow-up tracking device for ship-borne antenna

Abstract

The invention provides a mobile tracker for ship-borne antennas, and belongs to the technical field of the antennas. The mobile tracker solves the technical problem that an existing ship-borne antenna tracker is large in error. The mobile tracker comprises an anti-interference tank. A supporting plate is arranged on the opening of the upper end of the anti-interference tank, a sliding plate is fixedly arranged on the outer edge of the supporting plate, a first smooth curved surface is arranged on the outer surface of the sliding plate, and a second smooth curved surface is arranged on the inner surface of the upper end of the anti-interference tank. A hanging rod is fixedly arranged at the lower end of the supporting plate and arranged on the central line of the supporting plate and is perpendicular to the supporting plate, and a gravity block is fixedly arranged at the lower end of the hanging rod. A first servo motor is arranged at the upper end of the supporting plate, a case of the first servo motor is fixedly connected with the supporting plate, an output shaft of the first servo motor is fixedly provided with a rotating plate provided with an antenna assembly, and a swing mechanism capable of driving the antenna assembly to swing in the plane perpendicular to the rotating plate is arranged between the antenna assembly and the rotating plate. The mobile tracker has the advantages of being small in error, high in accuracy and the like.

Description

technical field [0001] The invention belongs to the technical field of antennas, and relates to a follow-up tracking device for ship-borne antennas. Background technique [0002] The biggest difference between a satellite antenna on a moving carrier and a fixed antenna on the ground is that the carrier of the antenna is a moving and swaying carrier, such as a satellite antenna on a ship, so a stable antenna platform is needed to isolate the swaying of the ship and realize the stability of the antenna in motion. The attitude is stable, and on the basis of the attitude stability, it can track and align the satellite during the movement. [0003] Traditional marine satellite antennas usually use a mechanical platform to isolate the disturbance of the carrier, and use a step-by-step tracking method to gradually align the antenna wave velocity with the satellite. Therefore, the key technology of the marine satellite antenna system lies in the stability and target tracking capabi...

Problems solved by technology

[0005] As we all know, keeping the carrier of the shipborne satellite antenna horizontal is one of the main technologies for antenna positioning and tracking. There is a problem of error accumulation in the way of achieving level. For ships that have been operating at sea for a long time, accumulative errors lead to inaccurate positioning, which will bring great safety hazards
