What is "A-GPS"?

Assisted GPS is a system commonly found in CDMA mobile phones in the US that offloads some of the processing requirements of a typical GPS receiver to a central server that can perform the calculations much more quickly. This allows the A-GPS receiver to work on devices with less computing resources than would be possible otherwise. A-GPS received a boost when the US government required mobile phones to support the E911 emergency calling system, which requires the caller's location to be known.

Also known as: "aGPS", "Assisted GPS"
