Using GPS Navigation 3 - 3
improves the performance of the Time To First Fix (TTFF) of GPS receivers by providing them with data that they
would ordinarily have to download from the GPS satellites. With t he A-GPS data, GPS receivers can operate faster
and more reliably.
A-GPS follows the Secure User Plane Location (SUPL) protocol which all ows the MC75 to communicate with a
location server. Refer to the EMDK Help file for information on setting up SUPL on the MC75.
