GPS (Global Positioning Systems) are the norm in those days. They help to move cars and ships on the surface of this beautiful place we call Earth. CAR also install GPS navigation systems in their cars to stay competitive. So for those who do not seem roads, no matter how hard they try to remember, this is good news. But perhaps interesting to see how the whole system.
For the GPS navigation function, it has 2 functions – complete (1) determine the location and (2) recommend guidelines. For reasons of simplicity, we’ll just watch the Navi on a car.
A GPS receiver is a passive instrument that information from satellites in the sky. These satellites are at specific locations, and they send information about their location to the receivers. The two essential pieces of information are time and distance.
A receiver, information of at least 3 satellites before it can calculate its own position. This is called triangulation. It is obvious that the position accuracy on the accuracy of the information that is transmitted by the satellite. The more precise information, the more accurate position.
For this reason, Sat Nav systems can only work if the communication between the receiver and the satellite is unlocked. It is, instead of the communication must be outside. Even then, the sky was as clear as possible. Sat navigation systems are known, if errors of calculation used for their production in forested areas.
In addition, some satellites are farther away than others. The farther the satellite, the less accurate calculations. Errors can be introduced when signals are reflected by tall buildings or other objects. The good news is, modern technology has managed to limit these lands somewhere between 10 to 20 meters.
Once /> is the location wurde, the task of the satellite has been completed. It belongs to the recipient, with important information to relay to the driver now. And where is the place where product differentiation in. Not all recipients of the work comes in the same way. The best receiver, as the TomTom 530, the unique features that help drivers navigate more easily control.
For example, the TomTom 530 as a unique feature, such as IQ routing known. IQ Routing calculates the estimated time to get from point A to point B on the basis of realistic point of speed. Normally, the maximum speed of roads is used in such calculations. But these calculations are not realistic, since rates are affected by road conditions. If the speed limit is 70km/hr, but the average speed is realistic 20km / h, 20km / h, the 530 TomTom uses in its calculations. A driver can easily see which ones to take the fastest routes and an easy decision.
In addition, the TomTom 530 also offers Advanced Lane Guidance realistic graphic representations of the crossings.
If you submit a receptor functionality combined with satellite technology, the results surprisingly effective.
