Personnel Navigation, Locating and Tracking

Robust, real-time positioning, tracking and locating of dismounted soldiers, firefighters and other first responders in GPS-denied environments

ENSCO, Inc. provides custom pedestrian navigation solutions that feature robust, real-time positioning, tracking and locating where GPS service is degraded or unavailable. This capability is useful to dismounted warfighters, firefighters and other first responders, and other critical personnel who are indoors, in dense foliage areas, urban canyons, open pit mines, and underground.

ENSCO scientists and engineers provide custom solutions that leverage various sensors, including:

Foot-worn MEMS-based inertial measurement units
Tightly-coupled GPS receivers
Digital magnetic compasses
Foot-to-foot RF ranging
Vision-based navigation sensors

The core of ENSCO’s capability combines advanced signal processing utilizing proprietary zero-velocity update with magnetic compass filtering algorithms in a light-weight, self-contained package.

ENSCO’s self-contained locating and tracking solution can be tailored to individual customer needs and applications. It can be integrated with other navigation or positioning systems, vision-based sensors, foot-to-foot radio-frequency ranging and other orthogonal technologies designed to increase positional accuracy over longer periods without GPS.

Applications for ENSCO Inertial Navigation Technology Solutions

Warfighter Positioning, Navigation and Tracking (PNT) – Enhance situational awareness for warfighters and commanders across a broad range of battlespace environments, including combat, special and covert operations, test and evaluation, and training
Battlefield and first responder health management – Provide integrated PNT and physiological monitoring solutions for warfighters and first responders under duress
First responders – Enhance situational awareness and guidance for incident commanders in dangerous environments and precise floor and room location of injured or downed personnel

Benefits

Practical Size – A stand-alone, self-contained package with low size, weight and power requirements
Accuracy – High positional accuracy for long periods of time without GPS (meter-level accuracy for more than two hours)
Flexibility – Minimal impact on operations and user ergonomics
Robustness – Accurate positional data during non-traditional methods of locomotion, including running, shuffling, crawling, standing still, and lying prone
