Location, mapping and navigation aids are routinely used by people and systems. They’re largely dependent on satellite systems like GPS. In circumstances where GPS is not available, for example, when underground, in large buildings or when GPS is disrupted, alternative navigation approaches are needed.
We used our heritage in computer vision to create a novel system that combines inertial navigation (movement sensors) with video analytics to create a system capable of locating itself, tracking movement and understanding orientation without reference to any external navigation systems.
The Roke Exploration Navigation System (RENS) is an entirely self-contained location and navigation system, delivered as a small matchbox-size unit, using widely available low-cost components. RENS can be attached to a user or a vehicle, allowing their location to be monitored. Applications range from car navigation to a firefighter building egress aid.
