Abstract
A system and method for mitigating the delay associated with using GPS technologies to determine the location of a mobile device. The system utilizes a two-stage location determination process. During the first stage, an estimated position of the mobile device is immediately provided based on the most accurate stored location information that is available to the system. If greater accuracy is still required, during the second stage a more accurate position of the mobile device is provided using GPS-based technologies.
