The Acoustic Multi-Mission Sensor (AMMS) exploits the benefits of novel Acoustic Vector Sensor technology, allowing the AMMS to detect, localize and track the full spectrum of acoustic battlefield signatures, covering Small Arms Fire (SAF),  rockets, artillery, mortars (RAM) and helicopters.

P-AMMS Sniper Localization

A Single AMMS (Personal AMMS) captures the shockwave of incoming rounds up to an extended Closest Point of Approach (CPA) range of 400 meters, providing an unprecedented accuracy, both angular (+- 2 %) and range ( +- 5 %)


RAM-SCORE is an AMMS array based system designed for training and proving ranges, providing fast and accurate location reports of both the points of impact (POI) and point of origin (POO) for various sorts of ammunition such as rockets, artillery and mortars.

UAV based | Acoustic Target Acquisition

Microflown's Acoustic Vector Sensors can be used for Acoustic Target Localisation on UAV platforms. Acoustic Vector Sensors on-board the UAV, together with local data processing, can detect and localise gunshots and artillery breaks on the ground.

Vehicle Mounted GUN-LOC and RAM-LOC Acoustic Vector Sensors (AVS)

Vehicle-mounted AMMS

Microflown AVISA's acoustic vector sensors can localise gunshots and rockets, artillery and mortars (RAM) in 3D space.This allows 'slew to cue' cameras, remote weapon stations and other sensors.





Microflown AVISA

Microflown AVISA from the Netherlands develops acoustic intelligence, surveillance, target acquisition and reconnaissance (ISTAR) systems, based on its worldwide unique Acoustic Vector Sensor (AVS) technology. Next to offering both off the shelf products well as customized solutions, Microflown AVISA also advises governmental agencies and NATO industry groups in the field of acoustic situational awareness.

Based upon an emerging new technology curve, Acoustic Vector Sensors (AVS) provide complete 3D acoustic situational awareness. Unlike traditional sheer sound pressure based acoustic localization systems, Acoustic Vector Sensors are broad banded. Hence Acoustic Vector Sensors are capable of detecting simultaneously all sorts of sound sources, ranging from high frequency Small Arms Fire to low frequency signatures like Rockets, Artillery and Mortars on the one hand and tonal sound sources like helicopters on the other hand.

As Acoustic Vector Sensors are small, compact and low power, this ITAR free passive truly multi-threat and multi-event localization capability can be used in arrays of Unattended Ground Sensors, but also be mounted on vehicles, unmanned aerial vehicles and helicopters.
