About positioning methods

Maps displays your location on the map using GPS, A-GPS, WLAN, or 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.
Wireless local area network (WLAN) positioning improves position accuracy when

GPS signals are not available, especially when you are indoors or between tall

buildings.

With cell ID based positioning, the position is determined through the antenna

tower your mobile device is currently connected to.
Depending on the available positioning method, the accuracy of positioning may

vary from a few metres to several kilometres.
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 WLAN.
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: Using WLAN may be restricted in some countries. For example, in

France, you are only allowed to use WLAN indoors. For more information, contact

your local authorities.
