Assisted Gps (A-Gps); Maps - Nokia C5–00 User Manual

36 Positioning
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.
The coordinates in the GPS are
expressed using the international
WGS-84 coordinate system. The
availability of the coordinates may
vary by region.
The GPS of this device is not for
professional positioning. GPS
connection time might also be affected
by weather, use environment, and
other condition of use. GPS should only
be used as a navigation aid and should
not be used for emergency or task
which requires more precise
positioning.

Assisted GPS (A-GPS)

Your device also supports assisted GPS
(A-GPS).
A-GPS requires network support.
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
English
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.
To disable the A-GPS service, select
Applications

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.
The access point for A-GPS can be
defined in positioning settings. Only a
packet data internet access point can
be used. Your device asks you to select
the internet access point when GPS is
used for the first time.
