■ 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.
