Abstract
Abstract The navigational system, device and method of the present invention provide navigational information to the user derived from data signals received from a plurality of transmitters (20,22,24,26). The range to each of the plurality of transmitters (20,22,24,26) is then computed based upon the corresponding data signal received from the transmitters, and a current position relative to each of said plurality of transmitters is then determined. Geographical data relating to at least the current location of the user module 32 is stored in a memory 40, and selected geographical data relating to the current location of the user module 32 is retrieved from the memory 40 to provide an audio or video display 44. The computed route between the current position of the user module 32 and each of a plurality of way-points is then transmitted to a control processor which compares the determined route with routes received from other user modules and predicts traffic conditions for transmission back to the user module so that the route may be altered accordingly.
