What's the "A" in A-GPS?

You’ve probably seen the A-GPS specification on your location aware smartphone. You know that GPS (Global Positioning System) is a way to determine your location using information from satellites. But, what does the “A” part of A-GPS indicate? The “A” stands for “Assisted”.

These “other” methods involve triangulation of signals from cell towers and WiFi access points.
