US-based Spatial Integrated Systems (SIS) and UK-based Cambridge Pixel have completed the integration of radar systems for US Navy Autonomous Surface Vessel (ASV) trials.

The SIS-Cambridge Pixel team integrated radar systems onboard a large surface vessel and several patrol boat-sized vessels.

The technologies integrated include the SIS Multi-Agent Robotic Teams (SMART) Autonomy System and Cambridge Pixel SPx Tracker and SPx Fusion software and radar interfacing hardware.

These demonstrations included several 300 nautical mile autonomous transits, three 1,000+ nautical mile fully autonomous transits, and multiple sub-task operational missions.

The teams demonstrated the vast untapped potential of maritime autonomous systems for the US Navy.

SIS programme manager Bob Cepek said: “From our long history working with Cambridge Pixel, we knew we would be successful in integrating and fusing multiple radars and sensors on different ships and boats with varying missions.

“We remain impressed by the Cambridge Pixel team’s responsiveness and speed in overcoming some tough technical challenges.”

The team integrated several sensors, including S and X band radars, from different manufacturers to improve the SMART Autonomy System’s perception capabilities.

Cambridge Pixel Software director Richard Warren said: “We are very excited to be working on these transatlantic autonomous vessel projects with the robotics engineers from Spatial Integrated Systems to integrate our radar tracking and fusion software with the SMART Autonomy System to enhance situational awareness on these crewless vessels.

“Our radar-agnostic tracking and fusion software works seamlessly with many different maritime and specialist radar sensors.

“Our goal on the recent trials for the US Navy was to configure our multi-hypothesis, multi-model SPx radar tracker and SPx fusion server to enhance the perception capabilities of SIS’s control system in this very demanding environment.”
