Autonaut is set to demonstrate its wave-propelled unmanned surface vessel (USV) at the Unmanned Warrior exercise, an event organised by the UK Royal Navy.

The exercise, which is scheduled to be held this October off the coasts of Scotland and West Wales, aims to promote the latest technologies developed by the country's defence companies.

During the exercise, participants from industry, academia and defence will operate more than 50 vehicles, sensors and systems.

"This is great opportunity to demonstrate the AutoNaut in a defence environment."

The engineless Autonaut USV will be installed with a sensor payload and deployed in the anti-submarine warfare category of the exercise.

Fitted with solar panels, the USV offers a noiseless platform for the deployment of passive acoustic monitoring (PAM) hydrophone arrays to provide a covert acoustic intelligence (AcInt) capability.

AutoNaut design manager Dan Alldis said: “This is great opportunity to demonstrate the AutoNaut in a defence environment.

“We will deploy the AutoNaut into the anti-submarine warfare (ASW) theme of Unmanned Warrior, where we will ‘hunt’ a number of underwater targets in realistic scenarios.

“We will also provide a wide range of near real time sensor data to the Royal Navy including radar signal measurement, day and low light 360° cameras and a multi-parameter metocean sensor package.”

Featuring wave foil technology, the AutoNaut USV propels itself using the motion of the ocean, which in turn allows it to be deployed offshore for longer periods to gather data from the ocean.

Autonaut has partnered with sensor providers in the UK, including Seiche Measurements, to develop the 25m thin line digital passive acoustic hydrophone array.

The array consists of 32 passive acoustic hydrophones, which can be individually tuned and configured by a remote operator at any time.

Teledyne Defence has developed and validated the Phobos Radar Threat Warner system, which has been integrated into the AutoNaut platform.

AutoNaut is also using Xylem Analytics developed YSI EXO2 Sonde multi-parameter water quality and oceanographic sensor, which is coupled with a weather station to provide valuable in situ metocean measurements.

The company is also collaborating with QinetiQ, which will provide a real-time communications link for the Autonaut USV during the exercise.
