A-GPS (Assisted GPS)

A-GPS (Assisted GPS)

Assisted GPS (A-GPS) is used to speed up start-up times of GPS-based positioning systems. GPS may have problems getting a lock when the signal is weak and in such a case A-GPS would assist in getting a lock.

This, however, is achieved by the use of an Assistance Server, so a data connection is required and charges may apply for the data transfer.
