Detect & Locate
Identify and geolocate cellular devices for missing persons, mass casualty events, and disaster response.
ARTEMIS Cellular Geolocation
When someone is missing, we help you find them.
Croix International turns every mobile phone into a rescue beacon, even when the cell network is down. Detect, locate, and communicate from the air, ground, or sea, then put it on every responder's screen.

The Problem
When towers fall, so does the search.
Hurricanes, earthquakes, wildfires, and avalanches take down the networks searchers rely on. Remote terrain never had coverage to begin with. But the missing person's phone is still out there, still searching for a signal.
ARTEMIS gives it one. It acts as a self-contained cellular network, so phones connect to it automatically and show up on the operator's map. No towers, no carrier, no guesswork.
Every second counts.ARTEMIS shrinks the search area from square miles to a single block, so teams go straight to the person instead of sweeping the map.

How ARTEMIS Works
From launch to first contact in four steps.
Capabilities
Five capabilities. One mission.
ARTEMIS does more than find a phone. It maps entire populations, talks to them, and feeds the picture to every team in the response.
Mass Location
Map thousands of devices to find densely populated areas and prioritize where teams go first.
Communicate
Broadcast SMS with critical information, safety routes, and resources to affected populations.
Common Operating Picture
Integrate with ATAK and other systems for real-time situational awareness and coordination.
All Environments
Aerial, ground, and maritime configurations for urban density or rural expanse.

Every phone in range, on the map
ARTEMIS sweeps the area from the air and every powered-on phone answers, even with the towers down. Each one becomes a point on the operator's map.
The ARTEMIS Family
The right payload for every platform.
From a small drone to a patrol aircraft, a backpack or a response vehicle, every ARTEMIS system detects, identifies, locates and communicates with mobile phones. The airborne systems reach beyond 30 km and are qualified to RTCA DO-160G, and Croix integrates each one with the platforms you already operate.

Request DatasheetsU-POD + ARTEMIS
ARTEMIS on any drone, in minutes.
The U-POD is a lightweight, rapidly deployable payload system that puts ARTEMIS cellular geolocation on unmanned aircraft. It mounts internally or externally on a range of UAV platforms, and its integrated air-to-ground link keeps installation and deployment time to a minimum.
Carrying the T-U or C-A payload, U-POD lets operators detect, identify and locate multiple phones in a single mission, with T-U detection ranges beyond 30 km in suitable conditions.
- Locate thousands of mobile phones in a few minutes
- Built-in 2.4 / 5 GHz air-to-ground link, no extra radio to integrate
