MobileNavigator	The time of complicated and frustrating inquiries on the right way
	in folded maps is over. From now on MobileNavigator, your
	navigation system, will guide you, based on satellite information,
	quickly and safely to your destination.
GPS-based	Based on satellites the Global Positioning System (GPS)
navigation	determines your current geographical position. The GPS has
	originally been developed as a weapon guidance system for the
	American forces.
Operating mode of	The GPS is based on 24 satellites, which are in orbit round the
the GPS	earth. They are permanently emitting the time and their current
	position. The GPS receiver receives this information and
	calculates the longitude and the latitude of its own actual
	position.
	The signals of at least three satellites are needed to determine
	the longitude and the latitude. With the signals of at least four
	satellites the elevation may be calculated, too. The determination
	has an accuracy of about 3 yards.
