Surveying is the technique and science of accurately determining the terrestrial or three-dimensional space position of points and the distances and angles between them.
Plane surveys - are the most commonly practised method of surveying and treat the earth as a flat or "plane" surface.
Even in that segment, I think only a minority of the existing survey receivers utilize GLONASS. But that's considering legacy receivers that have been in operation for many years.

Surveyor 1 obtained close-up views of some individual larger rocks, such as shown below.
Surveying observations are usually made with instruments levelled by means of spirit bubbles. Since these bubbles follow the influence of the earth's gravity the observations are made relative to the geoid.
Survey information may well be in the form of angle and distance measurements. Although there are GIS which can store and manipulate such geometric measurements, they are most often processed to derive Cartesian co-ordinates.

field survey Establishing and recording real world coordinates of physical features where they exist in the world. Checking and recording the accuracy of map feature depiction by visiting the real world features represented on the map.
Early surveys were often based on a local datum or reference system usually determined by astronomic observations. In 1900, enough observations were obtained to complete a national geodetic datum known as the U.S. Standard Datum.
Global surveys done to establish control networks (comprised of reference or control points) as a basis for accurate land mapping.
