Global Positioing System GPS equipment has changed the way Surveyors operate in the field. With distinct advantages in speed and accuracy over conventional survey methods, GNSS (Global Navigation Satellite System) is a rapidly growing technology for Surveyors to aquire accurate positioning. With many different accuracies and price ranges GNSS equipment is very practical for a multitude of surveying projects. RTK or Real Time Kinematic GPS surveying is based on radio communication between two GPS receivers. The system can provide real time positioning information to the rover receiver to centimeter level accuracy. With no line of site needed from the base unit to the rover certain types of surveys can be performed quickly and accurately with one operator.
