Introduction

The Nokia Wireless 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. With the GPS
module, you can determine your current position and direction.
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.
Note: There may be restrictions on using Bluetooth devices in some
locations. Check with your local authorities or service provider.
Using Bluetooth features, or allowing them to run in the background
while using other features, increases the demand on battery power and
reduces the battery life.

■ Global positioning system (GPS)

The GPS is a worldwide radio navigation system that includes 24 satellites
and their ground stations that monitor the operation of the satellites.
A GPS terminal (such as the Nokia Wireless GPS Module) receives low-
power radio signals from the satellites and measures the travel time of
the signal. From the travel time, the GPS terminal can calculate its
location to an accuracy of 82 feet (25 meters). In optimal conditions, the
accuracy may be within a few feet.
