Cambridge Pixel and SIS complete integration on ASVs for US Navy trials

US-maritime autonomy company Spatial Integrated Systems, Inc (SIS) and UK-based Cambridge Pixel have announced rapid innovation efforts in maritime autonomy and radar integration for US Navy Autonomous Surface Vessel (ASV) trials.

Together, SIS and Cambridge Pixel integrated a suite of complementary and interdependent systems including the SIS Multi-Agent Robotic Teams (SMART) Autonomy System and Cambridge Pixel SPx Tracker and SPx Fusion software and radar interfacing hardware.

The technologies were installed onboard a large surface vessel and several patrol boat-sized vessels. These demonstrations included multiple 300+ nautical mile autonomous transits – many in areas of heavy surface traffic, three 1000+ nautical mile fully autonomous transits, and the demonstration of multiple sub-task operational missions. These trials demonstrated the SIS-Cambridge Pixel teams commanding lead in this growing technological field and underscored the vast potential of maritime autonomous systems for the US Navy.

Bob Cepek, the SIS Program Manager for two of the efforts, 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.”

Ardent cooperation and innovation between the US and UK based teams were key to the success of this integration and the subsequent demonstrations. In just a few short months, the American and British teams integrated and fine-tuned the fusion of several sensors, including S and X band radars from different manufacturers, to improve the SMART Autonomy System’s perception capabilities. “Our most recent successes pave the way for additional collaboration in development and testing,” said Mr Cepek.

The market for ASVs is growing rapidly, driven by demand from navies and commercial enterprises worldwide for more effective maritime security – to combat terrorism, piracy and smuggling, to protect shallow waters and ports, and for environmental monitoring.

Richard Warren, Director of Software at Cambridge Pixel, 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. We look forward to further collaborations with SIS in this fast developing new and innovative market.”
