Positioning (GPS)
About GPS
The Global Positioning System (GPS) is a worldwide
radio navigation system that includes 24 satellites
and their ground stations that monitor the
operation of the satellites. Your device has an
internal GPS receiver.
A GPS terminal receives low-power radio signals
from the satellites and measures the travel time of
the signals. From the travel time, the GPS receiver
can calculate its location to the accuracy of meters.
The coordinates in the GPS are expressed in 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.
Your device also supports Assisted GPS (A-GPS).
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.
A-GPS is a network service.
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 a packet data internet access point
defined in the device to retrieve assistance data
from the Nokia A-GPS service. To define an access
point for A-GPS, press
, and select Tools >
Settings > General > Positioning >
Positioning server > Access point. A wireless LAN
