Assisted Gps (A-Gps); Hold Your Device Correctly - Nokia 5800 XpressMusic User Manual

Positioning (GPS)
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.
Important: Any unauthorized connection with or
otherwise access to a Nokia device by an unauthorized
third party device, accessory or software with the intent
to retrieve coordinates or other location related
information or to transmit such information outside the
border of South Korea may be illegal in this country, with
respect to which Nokia hereby disclaims any and all
liabilities to the extent permitted by applicable laws.
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
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.
Your device is preconfigured to use the Nokia A-GPS
service, if no service provider-specific A-GPS settings are
available. The assistance data is retrieved from the Nokia
A-GPS service server only when needed.
You must have an internet access point defined in the
device to retrieve assistance data from the Nokia A-GPS
service over a packet data connection. To define an access
point for A-GPS, select Menu
Location and Positioning
Access point. A wireless LAN (WLAN) access point cannot
be used for this service. Only a packet data internet access
point can be used. Your device asks for the internet access
point when GPS is used for the first time.

Hold your device correctly

When using the GPS receiver, ensure you do not cover the
antenna with your hand.
