L3 ASV (previously ASV Global) is a designer, manufacturer and operator of high-performance, rugged autonomous marine vehicle systems for military, government and commercial sectors.

ASV Unmanned Surface Vehicles

L3 ASV’s unmanned marine vehicle systems are used for a wide range of military and commercial applications. For military these include Mine Counter Measures (MCM), Intelligence, Surveillance and Reconnaissance (ISR), Anti-Submarine Warfare (ASW), and Fast Inshore Attack Craft (FIAC) for combat training. For commercial these include, Oil and Gas Exploration and Construction, Oceanographic Data Collection, Hydrographic, Oceanographic and Environmental Surveys.

L3 ASV also provides a broad range of technical services relating to autonomous marine vehicles, from concept design through to production and training. The company has a full complement of highly experienced staff as well as links with leading universities and manufacturing facilities.

ASView Control System

Remotely Control Surface Vessels

ASView-Bridge ASV User Control SystemL3 ASV has specifically developed and refined its ASView system for safe and reliable control of autonomous surface vehicles and has incorporated industry-leading research in collision avoidance and safe over-the-horizon operation. The complete system is comprised of the ASView-Bridge graphical user interface, ASView-Helm remote controller, ASView-Base radio enclosure and ASView-Core vehicle system.

ASView-Helm USV Remote ControlASView features direct remote control via ASView-Helm, assisted remote control, and a Mission Plan mode via ASView-Bridge UI that allows users to define lines, orbits and/or station keeping waypoints. It can be integrated into vessels with a wide variety of power generation and propulsion engines, motors and devices.

ASView supports a broad range of navigation sensors including GPS receivers, gyro stabilised and satellite compasses, inertial navigation systems, marine radar systems, AIS, electro optical and infrared cameras and depth sounders.

ASView Control System for Unmanned Surface Vessels

The system is compatible with line of sight communications including UHF radio, mesh network radio or Wi-Fi, as well as the commercially available Iridium, Inmarsat or V-Sat satellite communications systems.
