A partnership between the companies Emesent and Teledyne FLIR Defense has resulted in a new technological solution capable of mapping contaminated environments without the use of GPS and without the need for human presence.

The integration of the Hovermap LiDAR system with unmanned platforms, including drones and a ground robot, allows specialized teams to visualize risk areas in three dimensions in real time, increasing safety in operations involving chemical, biological, radiological, and nuclear (CBRN) threats.

Hovermap is the central element of the innovation, using SLAM technology to generate accurate three-dimensional maps even in locations where satellite signals are unavailable, such as tunnels, dense urban structures, and underground facilities. By eliminating the need for GPS, the system ensures autonomous navigation and continuous spatial awareness—essential for missions in complex or hazardous environments where conventional robots could lose orientation.

The major operational advantage comes from combining this mapping capability with the MUVE R430 radiation sensor, installed on the SUGV 325 ground robot. While the sensor measures radiation levels, Hovermap records the position and shape of the environment, enabling the creation of georeferenced 3D maps that precisely indicate where the highest-risk areas are located. This information is transmitted in real time, allowing external teams to monitor the situation without direct exposure to danger.

In addition to overcoming common limitations in GPS-denied operations, the solution also opens the door to future advancements. The companies are already working to expand the technology to include other types of sensors, which could enable integrated detection of chemical and biological threats within the same system. As such, the initiative represents an important step forward in the evolution of autonomous tools designed for safety in critical scenarios.
