Tracking/Positioning:
GPS
A-GPS (abbreviated generally as A-GPS and less commonly as aGPS) is a system that often significantly improves startup performance-i.e., time-to-first-fix (TTFF), of a GPS satellite-based positioning system. A-GPS is extensively used with GPS-capable cellular phones, as its development was accelerated by the U.S. FCC 911 requirement to make cell phone location data available to emergency call dispatchers.
