One of the most obvious uses for GNSS systems is the realization of surveys and production of maps. Although a simple standalone GNSS Receiver might not have the required precision for some survey requirements, most of these requirements can be fulfilled using high-end dual frequency multi-constellation receivers built specifically for surveying and by using GNSS Augmentation techniques.
The use of GNSS techniques in geodesy have revolutionized the way geodetic measurements are made. An increasing number of national governments and regional organizations are using GNSS measurements as the basis for their geodetic networks[1].
Land Surveying
Land Surveying is the processes of measuring the distances and angles between different points, on the surface of Earth. Satellite navigation has been extensively used by land surveyors since the late 1980s, primarily for geodetic control networks and for photo control.
Nowadays, GNSS is used to determine precise locations all over the globe, in any weather conditions. It is faster than other surveying methods, but it is not as accurate without with proper augmentation techniques.
GNSS systems are now available for many surveying tasks, including establishing control, setting out, real-time deformation monitoring, or on-board camera positioning for aerial photography.
