The Global Positioning System (Navstar-GPS) has modernized and allow greater ease in surveys related to activities that require placement in real time. This system consists of a constellation of satellites around the Earth providing a service for 24 hours three-dimensional positioning, velocity and time information to the users. However, certain atmospheric factors and other sources of error can affect the accuracy of GPS receivers. Thus, users can make more precise data collected with the Differential GPS (DGPS). It consists of a network of towers that receive the GPS signals and transmit the signals through fixed radio transmitters. It is effective to support activities which require continuous positioning in real time, which are required...
