Abstract
An indoor navigational system determines a location of a moveable object in an indoor area and displays this location to a user. The system includes one or more dead-reckoning sensors, one or more absolute position sensors, and a processor. The processor determines the location of the moveable object based on signals received from the sensors. The system also includes a display device to display the location of the moveable object in a graphical representation of the indoor area based on messages from the processor indicating the location of the moveable object.
