Personal Dead-Reckoning System for Firefighters

Report Date: August 2010

There are various personal localization systems being developed to help commanders to track firefighters inside a structure and to reduce firefighter lives lost from being trapped, lost, or disoriented during structural fires. This presentation details a Personal Dead-Reckoning (PDR) navigation system to monitor the location of a firefighter inside a building. The system uses an inertial measurement unit embedded in the heel of a firefighter boot. Inertial systems have historically had issues with positional error increasing and drifting with time, leading to large errors in location. This PDR system removes this drift error from the accelerometers and gyros in the inertial measurement unit resulting in excellent positional accuracy in all three axes, including elevation. This system could enable firefighters’ positions to be tracked real-time without requiring any additional equipment to be set up on scene.
