Global Positioning System (GPS) is a satellite navigation system that provides location and time information in all climate conditions. The GPS can be used for navigation in planes, ships, and cars. The system gives critical abilities to the military and civilians and provides continuous real-time, three-dimensional positioning, navigation, and timing worldwide.
We can find significant differences in performance and precision, depending on the GPS receiver quality. We can have a GPS receiver that is low cost, which has errors in the range of a few meters (5 m -10 m) and is commonly used in various applications requiring less precision, such as map routing. In other cases, we can have expensive GPS devices, configured as differential GPS (DGPS). This DGPS can achieve great results in terms of precision, with location errors less than 10 cm, and...
