GPS vs. Assisted GPS (AGPS)

An usual GPS receiver uses satellites to determine its position. It receives signals from different satellites at a time and compares the runtime difference of them. In order to compute a position, the GPS receiver has to know the exact position of every satellite. As the satellite orbit may vary, orbit data is provided by the GPS satellites. This is the so-called almanac, which can be downloaded from the GPS satellites. The longer your GPS receiver was not used, the longer it will take to acquire your exact position. Having moved far away from the position you used GPS the last time will make this worse (e.g. after travelling by plane). Depending on your GPS equipment and view of the sky, a so called cold start will take one minute or more.

AGPS is a GPS "assisted". The GPS receiver in your phone gets some assistance, but it still will work without that like a GPS receiver without the "A". How does this work? You need almanac data in order to acquire a position. Depending on conditions, it may take a minute or longer to get this data from GPS satellites. AGPS just downloads the almanac data, using the Mobile Network, which is way faster than using the satellites. Also, knowing your raw position will quicken the process of getting a GPS lock. AGPS acquires a raw position of the device by triangulating adjacent cell towers. AGPS is using certain techniques that will speed up the process of acquiring your position using a GPS device by using certain mobile network features. Every AGPS device should work as a normal GPS device, if mobile network is not available. Consider AGPS just as the "Plus" option, of the normal GPS!
