Abstract
An Interactive Real-Time Distributed Navigation system is disclosed. In the present invention a user's location is determined by generating a position signal at the user's location. Through wireless communication between the user and distributed navigation servers, the user is presented with a list of candidate locations. The user's choice from the candidate list are then used by the navigation servers to obtain an accurate measurement of the user's location. Having established a user's location, the system proceeds to provide navigational prompts to the user to reach a final destination.
