Global Positioning System (GPS) only works with the Global Navigation Satellite System that enables the GPS receiver to determine location, speed, direction, and time with the help of microwave signals right. This was developed by the Department of Defense United States, and left the official were baptized as a GPS. Generally GPS is widely used throughout the world as an important tool for making maps, periodic land, business and scientific use. Also an ingredient in the products of scientific research of earthquakes, and synchronization of telecommunications networks. This is the third of three or more GPS satellites, calculate the GPS position.

Generally, GPS is divided into three segments, especially the space segment (SS), control segment (CS), and the user segment (U.S.). To calculate the position and the GPS receiver, it takes time, position and delay the satellite receives the test signal. Position accuracy depends mainly on the satellite signal and the delayed position. With the support of higher education-chiprate P (Y) signal, the position accuracy can be improved. The same 1% bit time accuracy, high frequency P (Y) produces the signal accuracy of about 30 centimeters.

Obviously, the weather plays an important role in the speed of GPS signals. Each pattern of inconsistency in the atmosphere can affect the speed signal conditions when they passed through Earth's atmosphere and ionosphere can affect their speed as they passed through Earth's atmosphere and ionosphere.

At that time in the cold war the U.S. decided to develop a GPS. The launch of Sputnik by the Soviet Union an incentive for the development of NASA's project to track the movement of the satellite Sputnik which later started using for civilian purposes. In the current purpose GPS range finding ways for drivers to collect information on the weather.
