The Extended Embedded Pedestrian Tracking System (EEPTS) provides real-time dead-reckoning personnel tracking from a single body-worn inertial sensor. Designed for warfighter tracking and integration into defense systems, it reconstructs motion paths without GPS, RF, optics, or external infrastructure. Onboard AI processing generates the path within the sensor, eliminating the need for an external processing host or post-processing.
Wearable locations include the chest, shoulder, waist, and back, with tracking independent of mounting position, orientation, and user. The system recognizes walking, jogging, running, and crawling, and operates across indoor, outdoor, subterranean, urban, and undeveloped terrain. Specified positional error is ≤3% of distance traveled, expressed as ≤3 meters per 100 meters CEP.
Real-time outputs include latitude and longitude or positional offsets in meters, alongside full 3-Space AHRS/IMU functionality. EEPTS is offered within the 3-Space Sensor V3.0 family and as a linkable/loadable binary module for qualified users. A development kit, Sensor Suite and EEPTS evaluation mapping applications, and Python and C APIs provide resources for evaluation and integration.
