UNIVERSAL FIELD STAND FOR CHECKING GEODETIC INSTRUMENTS Russian patent published in 2021 - IPC G01C25/00 

FIELD: metrology.

SUBSTANCE: proposed invention relates to the field of metrology and can be used for metrological certification of geodetic instruments. The universal field stand for checking geodetic instruments contains a fixed center, around which geodetic points are fixed in eight directions along circles with radii of 5, 7, 10, 15 m, consisting of metal pipes with spherical heads. At the same time, the fixed center is a geodetic point equipped with a device for forced centering, fixed on the ground by a center of type 190, additional geodetic points are introduced, fixed on the ground by centers of type 162, located in eight directions around a circle with a radius of 50 m from the fixed center, in addition, introduced are geodetic points equipped with devices for forced centering, fixed on the ground by centers of type 150, located in eight directions along circles with radii of 50 and 200 m from the fixed center, moreover, geodetic points, fixed on the ground by centers of types 162 and 150, located in a circle with a radius of 50 m, alternate with each other, as well as all the above-mentioned geodetic points and the fixed center have coordinates and heights obtained in a single coordinate system.

EFFECT: expansion of functionality by ensuring the verification of four types of geodetic instruments: levels (optical and digital), electronic total stations, optical range finders, GNSS receivers with the required accuracy.
