Systems and Methods for Accessing Data Over a Short-range Data Link to Enhance the Performance of a Navigational Unit

摘要

A method for accessing data from a secondary device to enhance position data of a navigation unit is described. A short-range data link is established between a navigation unit and a secondary device. Secondary time data is received from the secondary device over the short-range data link. Secondary position data is received from the secondary device over the short-range data link.
