Beidou/GPS multi-frequency-point antenna for deep sea intelligent buoy

Abstract

The invention provides a Beidou / GPS multi-frequency-point antenna for a deep sea intelligent buoy. The Beidou / GPS multi-frequency-point antenna for a deep sea intelligent buoy includes a multi-frequency-point Beidou / GPS antenna, an antenna feed line and a pressure hull, wherein the pressure hull comprises a threading pipe, a flange and a radome; the radome is located at the top of the pressure hull and is sealedly connected to one side of the flange; the multi-frequency-point Beidou / GPS antenna is arranged in the radome; the threading pipe is sealedly connected to the other side of the flange;and the antenna feed line penetrates the threading pipe to connect the multi-frequency-point Beidou / GPS antenna and a Beidou module in a buoy compartment. The Beidou / GPS multi-frequency-point antennafor a deep sea intelligent buoy can ensure that the intelligent buoy can work in an underwater environment with a water depth of 4000 meters, and the Beidou / GPS multi-frequency-point antenna can effectively transmit or receive electromagnetic wave signals of four frequency bands of a Beidou first generation S / L, a Beidou second generation B1 and a GPS L1 after the deep sea intelligent buoy floatson the water surface, and can provide guarantee for deep sea intelligent buoy satellite positioning and implementation of a communication function.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a Beidou / GPS multi-frequency point antenna used for deep-sea intelligent buoys. Background technique [0002] Smart buoys for the global deep ocean can break through the limitations of existing ocean observation technology, realize observation of oceans deeper than 2,000 meters, expand the temporal and spatial coverage and monitoring scale of ocean observation, realize ocean three-dimensional detection, and can carry physical, chemical, biological Various sensors such as sensors can achieve high-precision, low-drift deep-sea long-term observations, and have important applications in marine environmental monitoring, oceanographic research, ocean formation, and marine disaster forecasting. After the smart buoy completes the observation of the ocean profile, the acquired ocean data needs to be uploaded to the shore station in time for storage and analysis. In deep s...

AI Technical Summary

Problems solved by technology

Due to the increase in deep-sea pressure, higher requirements are placed on the pressure resistance and sealing of satellite antennas. At present, there is no Beidou antenna product that meets the pressure resistance requirements of 4,000 meters of water depth.
