The New RTK—Changing Techniques for GPS Surveying in the USA
The private sector surveyor in America stands poised to enter a new era of control surveying. Traditional methods of Global Positioning System (GPS) static and single base Real Time Kinematic (RTK) control surveying found in most surveying and engineering shops, will soon give way to integrated networks of reference stations interpolating corrections for the point of survey rather than at the base station. Rather than using densely spaced "permanent" or passive physical monumentation, the trend is towards using surveying from much sparser physical networks and establishing site coordinates utilizing the Continuously Operating Reference Station (CORS) system as truth. However, even these newer approaches of post-processed static GPS surveying are yielding in many venues to the rosier cost-to-benefit ratio of using networked RTK.
