SDR-based mobile phone detection & location for search & rescue

ARTEMIS

The ARTEMIS MPDLS (mobile phone detection and location system) is a versatile SDR-based system that can be used to detect and geolocate missing persons through mobile phones and cellular devices, with unmatched speed and range. It is compatible with all generations of cellular technology and all frequency bands around the world, and can interact with thousands of devices simultaneously.

The system requires no cellular network operator interaction, acting as a simulated Base Transceiver Station (BTS) or cell tower and searching for the unique IMSI and IMEI numbers that identify the user and device. Upon detection, the system handshakes with the device, extracts the data from it and if it is a device of interest, geolocation takes place and an icon is placed on the map. In mass mapping mode, the system can display all devices in a particular area, allowing operators to select a specific target for geolocation. Devices can also be filtered by country of origin.

ARTEMIS utilizes proprietary geolocation techniques that are faster and more accurate than traditional direction-finding methods, and require only two small antennas. It can detect and geolocate phones in areas of up to 35km radius in 2G, and 12km radius in LTE, depending on aircraft altitude and the surrounding terrain. Geolocation accuracy is approximately 150m for 2G and 30-40m for 4G.

ARTEMIS is ideal for search and rescue, law enforcement, and border and maritime patrol, and is available in a number of different variants to suit a range of requirements and airborne platforms. The fully ruggedized and waterproof ARTEMIS-Flex is also available for deployment on vessels and small land vehicles such as snowmobiles.
