Global Positioning System. A Global Positioning System (GPS) uses a constellation of satellites and earth stationed receivers to determine geodetic positions (latitude and longitude) on the surface of the earth. WSDOT personnel use this survey technology. (See the Highway Surveying Manual for more detailed discussions.) GPS technology is changing rapidly. The key point is for the designer and surveyor to select the best tool (GPS or conventional applications) for doing the survey fieldwork. Often, a combination of GPS and conventional (Total Station) surveying is appropriate.
