Method and apparatus for initializing an approximate position in a GPS receiver

摘要

A method (200, 600) and an apparatus (700) for a wireless portable communication device (102) for determining coarse position information are provided. The wireless portable communication device (102) receives information about a plurality of visible satellites (106, 108, 110), and determines a coarse position of the wireless portable communication device (102) and uncertainty parameters expected at the coarse position, using the determined coarse position and uncertainties to acquire satellites.
