Optimization design of maritime communication buoy:research on technology integration based on VHF and Beidou system
There are problems with insufficient accuracy and low data exchange efficiency in traditional VHF and Beidou system positioning.Based on this,this article designs an integration scheme based on VHF and Beidou system technology.The scheme uses a domestic FPGA chip,model PH1A90SFG484,which can process multiple signal channels simultaneously in a short time,greatly improving the accuracy of frequency measurement.The experimental results show that the accuracy of the proposed scheme reaches 1×104 Hz.By optimizing the interface design,efficient data exchange between devices is achieved,providing strong support for the design of communication buoys.
