For most combatants it is terrifying to come under hostile fire, and especially so when they are unsure from where the firing emanates. Dutch firm Microflown AVISA (Stand 10-B33) has the solution with its Acoustic Vector Sensor (AVS). This extremely small device is derived from the company’s proven acoustic multi-mission sensor (AMMS), which is already of low size, weight and power (SWaP) for use on platforms ranging from vehicles and boats to helicopters and unmanned aerial vehicles (UAVs).
Here at IDEX, the company is showing what it claims to be a world first in an acoustic UAV payload, which locates sniper and mortar fire positions with a directional accuracy of typically 1.5°. Co-operating with WB Electronics, Micro-flown AVISA is demonstrating the AVS fitted to the Polish FlyEye UAV.
Also on show will be related equipment in the AMMS family, including the Forward-Flown AMMS, which is making its public debut, and the vehicle-based V-AMMS, which is now fielded by the Netherlands armed forces.
Microflown AVISA states that its highly accurate and reliable localisation systems boast a multi-threat capability, allowing for the location of small arms fire and rockets, as well as artillery and mortars.
