1 INTRODUCTION
The Direction of Motion – Dismounted Soldier Tracking (DOM DST) Evaluation Kit showcases PNI’s
technology to accurately track soldiers even when GPS is unavailable. Unlike other inertial tracking
technologies, PNI’s Direction of Motion (DOM) location tracking algorithms determine the direction of
the soldier’s path of travel
independent
of the soldier’s body pose or any device to body-frame offsets.
For example, the DOM DST will continue to track a soldier’s location even if they are walking backwards
or sideways.
PNI Sensor has invested IR&D over the last 7 years in developing inertial tracking algorithms that solely
employ consumer-grade MEMS inertial sensors in combination with our RM3100 magnetometers.
Hence, the DOM DST module is a self-contained low SWaP-C tracking unit that can be body worn and
deliver fine-resolution, step-by-step tracking and location in GPS-denied or compromised environments.
