Accuracy
As for the accuracy of GPS navigation systems, there are different figures on the subject. Sentences are fragmented and difficult to clearly say how accurate or inaccurate is the system, since there is a good point of reference. With the satellite navigation, system can determine its position with an accuracy of several meters. However, this system is not sufficiently precise to be able to perform with all the measurements, such as land surveying, or navigation of aircraft landing. When the need for greater precision of measurement is used DGPS system, the so-called. Differential GPS. Just as the principle of operation of the system of GPS, so everything here is very complicated and difficult it is to describe the "normal". You already have quite a complicated concept, which, without adequate knowledge cannot be understood. If I would like to describe accurately and clearly, take a very long time, a and so would probably not understandable to many. It passed by me to the purpose, because no one would rather not use this knowledge in practice.Well, we can, roughly the value of what we can determine the accuracy of the point. Some give 25 meters, while the other 15, and yet others much less. Very often we can also meet the terms that the more sensitive device, the more it is exactly.Generally speaking, the accuracy of GPS navigation systems, we can write many things, but in fact the most important information is already given above, generally in this area, people want to know just how much is accurate within meters of the accuracy of GPS systems.
