摘要
A method and apparatus for faster global positioning system (GPS) location using pre-computed spatial location data are described. In one embodiment, a method includes acquiring a pre-computed spatial location of a mobile platform device (MPD) that is computed when a GPS receiver is disabled due to the spatial location of the MPD. In one embodiment, the pre-computed spatial location is determined by a non-GPS based spatial location technology when a receiver is disabled due to the spatial location of the MPD. During the periodic computation of spatial location data, the GPS receiver may be monitored. In one embodiment, in response to activation of the GPS receiver, the pre-computed spatial location data is provided to the GPS receiver for identification and lock onto a predetermined number of visible satellites to reduce a time to first fix (TTFF) a current spatial location of the MPD. Other embodiments are described and claimed.
