DSEI 2015: New Boat-Mounted Sensor Enhances Maritime Situational Awareness

Microflown AVISA’s subsidiary Microflown Maritime developed a gunshot detection and localisation system for maritime use, with its boat-mounted sensor based on the proprietary Acoustic Vector Sensor (AVS) technology, measuring directional acoustic particle velocity. According to the company, the device offers a reliable directional accuracy of 1.5 degrees in gunshot detection. The Acoustic Multi-Mission Sensor (AMMS) has been upgraded and fully adapted for maritime applications, able to localise small arms fire from small craft at sea or from the shoreline.

According to the company, AMMS have been in use with the Dutch military since 2012. The device has been successfully tested in cooperation with the Royal Netherlands Navy, Microflown Maritime said. It was installed on FRISC (Fast Raiding Interception Special Forces Craft) platforms, with the sensor offering a true 360-degree situational awareness, accurately localising fire positions and displaying the direction and distance to the hostile shooters on an ‘easy-to-use’, ruggedised tablet. The sensor can detect shots and locate the shooter position whilst being targeted directly. Ranges up to 1,500m and miss distances up to 200m can be achieved. Grid coordinates of the hostile shooter position can then be handed over to the Battle Management System (BMS).

According to Microflown Maritime, the B-AMMS can be operated from -20°C up to 70°C, consuming less than 2W. It can be installed on-board any maritime ship, successfully localising shooters whilst moving with speeds up to 43 knots (80km/h) in various weather conditions (rain, wind speeds up to 6BFT, fog, large sea waves). This mounted system, when used on a naval ship, can even be used in conjunction with on-board systems or replace them when unfavourable weather conditions would normally create clutter in the other existing (on-board) detection capabilities, such as radar, Microflown Maritime said.
