AGPS

AGPS, short for Assisted Global Positioning System, is a method whereby another method of triangulation is used to augment traditional GPS location tracking. Typically when GPS receivers power on, they can take minutes to acquire the proper satelites for triangulation. AGPS speeds up the process by using another method of triangulation, typically cell phone towers or WiFi hotspots, to cut down the time from two or three minutes to 10-20 seconds maximum. Typically, AGPS is implemented in cell phones, since the phones already have another method for semi-accurate triangulation using two or more cell phone towers.
