With the Nokia Wireless GPS Module, you can determine your current position
and direction easily. The GPS module is a battery-operated device that uses
Bluetooth wireless technology to communicate positioning information to
compatible mobile phones, PCs, PDAs, and other devices.
Read this user guide carefully before using the GPS module. Check also http://
www.nokia.com/support or your local Nokia Web site for the latest version of this
guide, additional information, downloads, and services related to your Nokia
product.
■ Global Positioning System
The Global Positioning System (GPS) is a worldwide satellite-based radio
navigation system.
A GPS terminal can calculate its location to an accuracy of 25 meters. The
accuracy depends on the number of satellites, the signals of which the GPS
module receives. In optimal conditions, the accuracy may be within a few meters.
The antenna of the GPS module is located under the Nokia logo, and it should face
upwards. Some car windshields and windows may contain metal, which may block
or weaken the satellite signals.
If you stand still, GPS cannot detect which way you are facing, because it
determines your direction on the basis of your movement.
The Global Positioning System (GPS) is operated by the United States
government, which is solely responsible for accuracy and maintenance of
the system. 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 buildings and
natural obstacles, as well as weather conditions. The GPS receiver should
only be used outdoors to allow reception of GPS signals.
Therefore, GPS should not be used for precise location measurement, and
you should never rely solely on location data from the GPS receiver. This
GPS receiver does not support location of the phone by emergency
operators.
