Abstract

The paper describes a method to establish compatibility between an autonomous surface vessel control system and a Navico Broadband Radar BR24. The solution obtains radar imagery and control of the antenna unit over its standard Ethernet interface, making the proprietary controller unit optional. It presents devices, software and methods used for empirical protocol analysis and documents the findings. Protocol details for the following functions have been identified: Operation, zoom level, various filter settings, scan speed and keep alive. An open source implementation with basic operational functionality has been made available. It features a live network mode and a replay mode using captured network traffic. In live mode, controlling radar operation as well as zoom level is possible. In both modes the radar imagery stream is rendered and displayed.
