Abstract
A navigation system includes a navigation device that communicates with a data processing system. The navigation device includes one or more movement detectors that are configured to generate data that are indicative of movement of the navigation device, and a transmitter that is communicatively coupled to the one or more movement detectors. The transmitter is configured to transmit a signal that contains the movement data using a wireless communication protocol. The data processing system includes a receiver that is responsive to the signal from the navigation device and a processor that is communicatively coupled to the receiver. The processor is programmed to process the data to compute a location, position, and/or orientation of the navigation device.
