About GPS & A-GPS

GPS, is the short name of Global Positioning System, while a GPS device is means a device get positioning function, which can also used for navigation, such as GPS cell phones. GPS equipment provide permission and longitude information, and some may also evaluate elevation, although this is not considered properly correct or consistently available enough (due to the opportunity of transmission obstruction and other factors) to make use of specifically to start jet. GPS equipment are used in army, flying, sea and customer product programs.

A-GPS, also called Assisted GPS, it is a solution coming form GPS. It is a system which can, under certain conditions, improve the startup performance, or time-to-first-fix (TTFF) of a GPS satellite-based positioning system. It is used extensively with GPS-capable cellular phones as its development was accelerated by the U.S. FCC’s 911 mandate making the location of a cell phone available to emergency call dispatchers.

Chinese GPS phone
That is to say, A-GPS is used when the signel is weak, and one can use the the phone connect to internet to get information, but GPS get position under help of satellite, and then do navigation job according the maps installed in the phone.
Gernerly speaking, many Chinese android phones support GPS, that is to say, it is built-in GPS, real GPS, can searh for satellites and do navigation job. But some of phones is A-GPS, if  u need use your phone to navigate, must connect to internet.
However, GPS chip plays the decision role in GPS function, so the chip’s quality is very important. But many Chinese phone manufacturers won’t adapt the best GPS chip, in order to save cost. That is to say, maybe the GPS function won’t work very well, the signel may be weak or not stable. In this case, maybe A-GPS is your better choice.
