Abstract

There is no need to take important and risky measures to obtain highly accurate geographic data using the GPS. Entry into this new technology requires careful observation during the examinations of the costs, and correction of errors. The main motive behind the development of the GPS (Global Positioning System) is the need for highly precise navigational tools, which in fact determine the location, speed and time with very high precision. The U.S. Ministry of Defense plays a major role in the development of the GPS system. The main motive behind the development of this system is the urgent need for equipment that can easily assist the deployment of military and war machine and determine the position of individuals, planes and long-range missiles during training and military operations. This system has caused a transformation in the science of positioning. The GPS technology easily determines extremely tiny points at very high precision regardless of weather conditions, during the day or the night. It is also used to collect and access a wide range of geographic data.
