Project Overview

• Create a VDES system that can be used by the Coast

Guard

• Software Defined Radio
• Benchtop Model Using USRP

Background

• Important to communicate information for ships
• 3 systems, 2 channels, with different frequencies
• Each transmits different information
• Currently only AIS is implemented

Solution ~ Software Defined Radio

Hardware

• Coast Guard Radio
• AIS → ASM → VDE
• Transmitter → Receiver

Software

• Open-source
• GNU Radio Companion

○ MATLAB Code

AIS Receiver - MATLAB

AIS Transmitter - GNU Radio

AIS Receiver - GNU Radio

• Further testing and documentation of AIS code
• Document ASM code and layout algorithm
• Alter AIS Receiver Matlab code to receive ASM signals
• Alter AIS Transmitter Matlab code to transmit ASM signals

Whats Next?
