High-precision positioning marine satellite communication equipment

Abstract

The invention relates to the technical field of communication, and discloses high-precision positioning marine satellite communication equipment, which comprises a base, wherein a buffer groove is arranged in the top end of the base; a counterweight is slidably connected in the buffer groove; a plurality of buffer gears are fixedly connected to the counterweight and the bottom of the buffer groove; one end, away from the bottom of the buffer groove, of the counterweight penetrates through a notch of the buffer groove and extends outwards, and is fixedly connected to a supporting column; one end, away from the counterweight, of the supporting column is fixedly connected to a parabolic antenna through a rotating device; a high-frequency head is arranged in the parabolic antenna; the buffer mechanism comprises two symmetrically-arranged chutes; the two chutes are respectively arranged in the bottom end of the counterweight and the bottom of the buffer groove; and a first sliding block anda second sliding block are sequentially and slidably connected in the chutes from left to right. According to the high-precision positioning marine satellite communication equipment, the damage to the interior of an emitter due to shaking of a ship body can be reduced, and the service life of the device is prolonged.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a high-precision positioning maritime 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. When there are no obstacles such as islands on the propagation path, the propagation loss can be analyzed according to the propagation theory of smooth spherical earth. The relationship between the field strength and distance obtained by the actual measurement of sea propagation is given. A large number of actual measurement results show that: in the case of a ship sailing, if there are no obstacles in the propagation path and nearby waters, the signal electric field strength does not change much, the instantaneous value changes about ±3dB, and...
