Evidence of its use can be found dating as far back as 2700 BC when the Great Pyramid of Giza was...
How Accurate Is an RTN?
Many surveyors have realized the benefits of using real-time GNSS networks (RTN) for survey-grade positioning. Saving time, equipment, and personnel means saving project costs. The thing about real-time GNSS surveying, however, is that “rover expertise” needs to be applied in the field (not the office). Additionally, many factors involved with GNSS signalization, as well as...
