Popis: Receiving antennas of GNSS–stations are placed on buildings, special pedestals, the foundations of which are often located in the zone of significant soil deformations under the influence of variations in hydrothermal factors. This can distort the obtained results of monitoring the earth's surface and call into question the reliability of their interpretation. Depending on the characteristic conditions of the device of the base station of the global navigation satellite system, on the design solutions and the functional purpose of the buildings that are the bases for the location, appropriate decisions are made on the location of the GNSS station. The system of operation of the elements of the equipment of the base station of the global navigation satellite system, the design features of the receiving antennas, their attachment to building structures have been investigated. The preferential conditions for choosing a place for the installation and operation of the receiving antenna of a GNSS–station are indicated, groups of places for installing receiving antennas on the supporting parts of the roofs of buildings are highlighted. The efficiency of using GNSS–stations as a set of methodological, technical and organizational principles of activity in the global positioning system is considered. The components of the system for examining the external structures of buildings and structures are highlighted: a subsystem of structural solutions for building objects, the organization of examination of external structures, external factors of hydrothermal origin, a subsystem of design solutions for the operation of a GNSS–station, a subsystem for organizing installation and connection. An assessment of the main characteristics of the design solutions for the operation of a GNSS–station was carried out, in particular, the selection of structural elements of buildings and structures for installing the station antennas, the determination and processing of the coordinates of points.
