Roke Exploration Navigation System (RENS)
Roke Exploration Navigation System (RENS) is an inertial navigation system which helps you navigate confidently in buildings, tunnels, and underground environments where GPS fails. Keep your operations moving with Roke Exploration Navigation System (RENS), a proven computer vision tool that delivers accurate positioning and orientation data using only a camera and sensors.
Maintain Positioning, Navigation and Timing (PNT) capability in GPS-denied/intermittent environments using advanced computer vision and sensor fusion. RENS is an inertial navigation system helping to track your position and orientation in real-time through buildings, tunnels, and underground spaces.
Passive Navigation Without Satellites
Operations often require navigation in GPS-denied environments like buildings, tunnels, underground facilities, and urban canyons, which block satellite signals, leaving personnel and unmanned systems without reliable positioning.
RENS is an inertial navigation system that helps solve this using computer vision algorithms that track movement through any environment. A single camera, inertial sensors, and processing unit create accurate position estimates without external signals. Deploy on personnel or integrate with unmanned systems for continuous navigation capability.
Achieve sub-4% drift rates over distances up to 2km during hour-long missions. Maintain operational effectiveness when GPS jammers activate or environmental conditions block satellite access.
