A
system and method for locating, tracking, and / or monitoring the status of personnel and / or assets (collectively “trackees”), both indoors and outdoors, is provided.
Tracking data obtained from any number of sources utilizing any number of tracking methods (e.g., inertial navigation and
signal-based methods) may be provided as input to a mapping application. The mapping application may generate position estimates for trackees using a suite of mapping tools to make corrections to the
tracking data. The mapping application may further use information from building data, when available, to enhance position estimates. Indoor tracking methods including, for example,
sensor fusion methods,
map matching methods, and map building methods may be implemented to take
tracking data from one or more trackees and compute a more accurate tracking estimate for each trackee. Outdoor tracking methods may be implemented to enhance outdoor
tracking data by combining tracking estimates such as inertial tracks with magnetic and / or
compass data if and when available, and with GPS, if and when available.
