Microflown AVISA’s compound and border protection system provides a true multi-threat hostile
fire localization system against Small Arms fire (SAF) and Rockets, Artillery and Mortars (RAM).
The technology of the Compound Protection System is based on the Acoustic Multi-Mission Sensor
(AMMS), developed by Microflown AVISA.
The lightweight compound protection system uses at least seven AMMSs and a Command Post to
dramatically improve situational awareness during an attack. A Sensor Post consists of a single
lightweight and man portable sensor, equipped with a Geo-boom which makes the quick and
automatic positioning and orientation possible. The system provides 360° situational awareness.
Further, it provides grid location of the firing position. For RAM also the position of the
explosion of the grenade is known, and in case of a sniper the direction in which the bullet is
The Compound Protection System can be used for large protected bases (i.e. full scale
compounds) but also smaller scale bases (FOBs, COPs) that require shot detection capability. The
system is fully scalable and can be integrated with existing command & control systems.
The Compound Protection System can be utilized independently using its own power supply and
wireless network or it can easily be integrated into an existing infrastructure.
Powering on and off and all other system settings can be set from a distance via remote
wireless access by the AMMS C2 Server Software. Once powered, an AMMS automatically report any
detected hostile shooter location in real-time.
The AMMS has low Size, Weight and Power (SWaP). A sensor post has a total weight of 5kg and can
be carried by just one soldier. Due to the small footprint of the system, deployment is fast and
easy for both permanent and temporary use.
This fast deployable compound protection system is a game-changer: reliable, trainable and easy
to use, while providing grid locations of hostile fire positions in real-time.
• Broad banded and passive system with extremely small footprint
• Accurate detection and localisation of indirect and direct fire
weapons within seconds
• Fast and easy system deployment independent of existing
• Integration in a third party C2 systems is possible
• Operates under adverse weather conditions (e.g. rain, snow, sand
storms and fog)
Vehicle Based Acoustic Multi-Mission Sensor (V-AMMS) is a gunshot detection and localisation
system, based on the worldwide unique and extremely small Acoustic Vector Sensor (AVS)
technology developed by Microflown AVISA. V-AMMS is installed on vehicles and provides
the crew with a true 360° situational awareness. It locates fire positions and
displays the direction and distance to the hostile shooters on an easy to use
V-AMMS is installed on vehicles and provides the crew with a true 360° situational awareness.
It locates fire positions and displays the direction and distance to the hostile shooters on an
easy to use ruggedised tablet.
The V-AMMS technology is based on measuring the directional acoustic particle velocity. This
unique technology allows outstanding results with a directional accuracy of 1.5 degrees. This
combined with its low SWaP characteristics makes it a valuable addition to any intended or
existing sensor suite on board of manned or unmanned vehicles.
In comparison to traditional microphone based arrays, the V-AMMS has two main advantages:
Firstly, it is extremely small and compact due to Microflown’s unique and patented sensor
technology. It does not limit the 360 degree capability of RWS and EO system. Secondly, user
feedback for traditional shot detection systems spoke of high false alarm rates with random
directions in real mission use. V-AMMS has therefore been specifically designed to increase
performance while eliminating false alarms entirely.
Unlike other acoustic systems in the marketplace, V- AMMS measures the direction of the hostile
shooter instead of calculating it.
V-AMMS can be installed on any wheeled vehicle, including light armoured vehicles and
successfully can locate shooters while driving up to 60 km/h in rough terrain conditions. V-AMMS
masters true multi-shooting scenarios while being targeted directly. It can detect shots and
locate the shooter position when the bullet does not directly pass the vehicle. Ranges up to
1500m and miss distances up to 200m can be achieved.
The shooter location provided by V-AMMS can be used stand alone or in data fusion as part of a
sensor suite, cueing a RWS, radar or EO system towards the shooter position identified by
V-AMMS. Grid coordinates of the hostile shooter position can be handed over to the battlefield
management system, if available.
