Positioning	You can use applications such as Maps and GPS data
	to find out your location, or measure distances and
	coordinates. These applications require a GPS
	connection.
	About GPS
	The Global Positioning System (GPS) is a worldwide
	radio navigation system that includes 24 satellites
	and their ground stations that monitor the
	operation of the satellites. Your device has an
	internal GPS receiver.
	A GPS terminal receives low-power radio signals
	from the satellites and measures the travel time of
	the signals. From the travel time, the GPS receiver
	can calculate its location to the accuracy of metres.
	The coordinates in the GPS are expressed in degrees
	and decimal degrees format using the international
	WGS-84 coordinate system.
	The Global Positioning System (GPS) is operated by
	the government of the United States, which is solely
	responsible for its accuracy and maintenance. The
52	accuracy of location data can be affected by
	adjustments to GPS satellites made by the United
	States government and is subject to change with

the United States Department of Defense civil GPS policy and the Federal Radionavigation Plan. Accuracy can also be affected by poor satellite geometry. Availability and quality of GPS signals may be affected by your location, buildings, natural obstacles, and weather conditions. The GPS receiver should only be used outdoors to allow reception of GPS signals.

Any GPS should not be used for precise location measurement, and you should never rely solely on location data from the GPS receiver and cellular radio networks for positioning or navigation.

To enable or disable different positioning methods, such as Bluetooth GPS, press , and select Tools > Settings > General > Positioning > Positioning methods.

Assisted GPS (A-GPS)

Your device also supports Assisted GPS (A-GPS). A-GPS is a network service.

Assisted GPS (A-GPS) is used to retrieve assistance data over a packet data connection, which assists in calculating the coordinates of your current location
