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.

Système et procédé propres à raccourcir le retard associé à l'emploi de technologies GPS pour la détermination de la position d'un dispositif mobile. Le système met en oeuvre un processus en deux phases de détermination de positon. Dans une première phase, une positon estimée du dispositif mobile est fournie immédiatement sur la base des informations de position stockées les plus précises dont dispose le système. Si un surcroît de précision s'impose, une deuxième phase faisant intervenir des technologies GPS permet de localiser plus précisément le dispositif mobile.
