2.1Operating mode of your navigation system
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. |
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. |
