Traveling

Need directions? Looking for a restaurant? Your device has

the tools to get you where you want to be.

Positioning (GPS)

You can use applications such as GPS data to determine your

location, or measure distances and coordinates. These

applications require a GPS connection.

About GPS

The coordinates in the GPS are expressed in the 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 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.

Different positioning methods can be enabled or disabled in

positioning settings.

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 when your device is

receiving signals from satellites.

When you activate A-GPS, your device receives useful satellite

information from an assistance data server over the cellular

network. With the help of assisted data, your device can

obtain the GPS position faster.
