GPS depends on information from satellites to get the current location of the device. But in case of area where device is getting poor signals, it may face trouble in locating exact positioning data. In this case, GPS unit may need as long as 12.5 minutes to get exact current location. Hence, very slow startup performance of the GPS unit in case of poor satellite signals. Assisted GPS (abbreviated as a-GPS) is the system to improve the startup performance or GPS. It is used in GPS capable devices to offer faster positioning systems.
It is achieved with the help of a Assistance Server. Data connection is required to use this. When GPS signals are weak, device connects to assistance server on internet. A-GPS features depend mostly on internet data. In case of no internet connection, device will use satellite data.
A-GPS also gives better accudaracy
