RAM-LOC is a modular system of networked smart sensors, called AMMS (Acoustic Multi-Mission Sensors). AMMS detect and locate weapons passively, using the acoustic emission of the weapon, in combination with meteorological and terrain data.

RAM-LOC is designed to be used as part of a C-RAM (Counter Rocket, Artillery and Mortar) system, locating enemy firing positions over a wide area. Each RAM-LOC system typically comprises multiple remote operated ground sensors, a wireless communication system, and a command centre processor.

The sensors are mobile, fast deployable, and modular, and therefore can be configured to work in all areas and environments. Typical use would be for the protection of fixed perimeters such as border lines and forward operating bases (FOBs), or for temporary locations such as rest over nights (RONs). 

RAM-LOC is also suitable for supporting weapon locating radar (WLR), reconfirming targets (as per rules of engagement) and reducing false alarms which can bring base operations to a halt for unnecessary periods of time.

As RAM-LOC works best at close range and radar is more suited for long range detection, the systems complement each other well. It also acts as an unjammable close‑range backup during radar affecting weather, for where line of sight is obscured by terrain dips or hills, and for low trajectory weapons where projectiles stay close to the ground and out of sight of radar. Crucially, RAM-LOC is a passive system, so it cannot be located and jammed like radar.

Detection of an event by one of the ground sensors results in information being sent to the command centre, typically time stamp, classification of sound, and bearing and elevation to the source. The bulk of the processing is done at each ground sensor individually, so there are only very small packets of text data to transmit to the command centre. This data, from multiple sensors, is then collated and processed centrally, and the calculated locations are presented both in tabular form as well as in a graphical format, e.g. on a map or satellite image of the area. The points of impacts (POI) and points of origin (POO) are presented as grid coordinates. All information can be exported or printed out in hard copy for further reporting and de-briefing. With the command centre software, the ground sensors can be remotely accessed, allowing for easy and convenient configuration.
