What is aGPS?
aGPS is Assisted Global Positioning System. It was introduced to enhance performance. With conventional GPS systems, it is often difficult to provide reliable positions under poor signal conditions, for example, if you are surrounded by tall buildings (as a result of multipath) or if the satellite signals are weakened when you are indoors or under a tree. Some newer receivers fare better. The aGPS system, consisting of an integrated GPS receiver and network components, boosts performance beyond that of the same receiver in a stand-alone mode.
