About positioning methods

Maps displays your location on the map

using GPS, A-GPS, WLAN, or network (cell

ID) based positioning.
The global positioning system (GPS) is a

satellite-based navigation system used

for calculating your location. Assisted GPS

(A-GPS) is a network service that sends you

GPS data, improving the speed and

accuracy of the positioning.
WLAN positioning improves position

accuracy when GPS signals are not

available, especially when you are indoors

or between tall buildings.
With network (cell ID) based positioning,

the position is determined through the

antenna system your mobile device is

currently connected to.
When you use Maps for the first time, you

are prompted to define the internet access

point to use to download map

information, use A-GPS, or connect to a

To avoid network service costs, you can

disable A-GPS, WLAN, and network (cell ID)

based positioning in your device

positioning settings, but calculating your

location may take much longer. For more

information about positioning settings,

see the user guide of your device.
The Global Positioning System (GPS) is

operated by the government of the United

States, which is solely responsible for its

accuracy and maintenance. The 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. GPS

signals may not be available inside

buildings or underground and may be

impaired by materials such as concrete

and metal.
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.
The trip meter has limited accuracy, and

rounding errors may occur. Accuracy can

also be affected by availability and quality

of GPS signals.

Note: In France, you are only

allowed to use WLAN indoors.
Depending on the available positioning

methods, the accuracy of positioning may

vary from a few metres to several
