Marine anti-interference satellite communication equipment with accurate positioning function

Abstract

The invention discloses a marine anti-interference satellite communication device with an accurate positioning function, which comprises a supporting column, the top end of the supporting column is fixedly connected with a parabolic antenna through a rotating device, the bottom end of the supporting column is fixedly connected with a buffer base, and a plurality of anti-seismic assemblies are arranged in the circumferential direction of the buffer base. The outer side of each anti-seismic assembly is connected with a baffle through a fluctuation unit, the baffles enable fluctuation of sea waves to inwards generate irregular pushing, pressing and stretching acting force, and the irregular pushing, pressing and stretching acting force is buffered and counteracted through the fluctuation units and the anti-seismic assemblies. Buffering counteracting in the vertical direction and the horizontal direction is achieved through the anti-seismic assemblies arranged in the circumferential direction, buffering of overall shaking is achieved through the buffering base arranged at the bottom, the shaking amplitude is further counteracted through the fluctuation units arranged on the outer side in the circumferential direction, the sea surface anti-interference capacity of the communication equipment is improved through multi-stage buffering counteracting on irregular impact force of sea waves, the direct impact force of the internal structure is reduced, and meanwhile the precise positioning function is achieved.

Description

technical field [0001] The invention relates to the technical field of maritime communication, in particular to a precisely positioned maritime anti-jamming satellite communication device. Background technique [0002] Maritime mobile communication generally refers to the communication between land base stations and ships and ships. Its radio wave propagation path is almost all on the sea surface, and the propagation conditions are better than land. Maritime mobile communication equipment mostly uses satellite receivers to receive and propagate signals. The satellite receiving system is a complete set of satellite ground receiving stations composed of parabolic antennas, feed sources, high-frequency heads, and satellite receivers. The reflection of the satellite signal energy converges into one point to realize the function of real-time positioning.

Problems solved by technology

[0003] However, in the prior art, when the hull is traveling on the sea surface, the hull shakes in waves because the sea surface is not calm all the time, causing the satellite receiver fixed on the hull to shake with the hull, and the constant shaking will cause damage to the internal equipment of the satellite receiver. At the same time, when the shaking of the hull is large, the shaking time will be longer and it will be more difficult to recover, resulting in a decrease in the accuracy of the received signal
