Chat-Over-AIS System Test Report Obangame Express 2019

Abstract

This report focuses on exploring ways to utilize the Automatic Identification System (AIS) in innovative ways to deliver non-AIS data, such as coastal RADAR, using AIS channels. The AIS is an automatic tracking system used on ships and by Vessel Traffic Services (VTS). AIS systems send vessel position reports using dedicated Very High Frequency (VHF) frequencies. While AIS is normally used for collision avoidance, there are other potential uses for AIS that were investigated in our study. Those potential uses are detailed in this report. Use of the AIS systems as an information conduit channel takes advantage of AIS system capabilities to exchange messages with a custom payload. The payload of the CHAT-over-AIS messages contains chat text messages sent between AIS transponders as a means to relay text data instead of relying on VHF radio for communication between either ship-to-ship or ship-to-shore.
