Abstract
A system and method for determining the location of a mobile device is provided. Such a method includes receiving an interior map, determining a first location to be an absolute location of a mobile communication device, locating the absolute location at a first position on the interior map, relocating the mobile communication device to a second location, estimating the second location of the mobile communication device based on an output of one or more sensors and modifying, using a computer-based system, the estimated second location based on a comparison of the estimated second location to the interior map.
