Abstract: A system, device and method for assisting navigation are disclosed. The system comprises at least one positioning support device and a personal portable wireless user device. The positioning support device is operable to be placed near a navigation feature and to communicate appropriate navigational information, including absolute position and relative position with respect to a navigational feature. The user device is operable to receive the navigational information and communicate it to a user. The method operates to permit users to independently navigate local, overland or underwater areas and is especially useful for persons who whose vision may be impaired.
