METHOD OF CONTROLLING GEOMETRY OF LARGE-SIZE OBJECTS Russian patent published in 2020 - IPC G01S5/14 G01S19/14 G01S19/44 

FIELD: radio navigation.

SUBSTANCE: invention relates to radio navigation and can be used to control geometry of large-size objects during their operation. Method includes measuring spatial coordinates of node points using navigation radio signals of satellite radio navigation systems (SRNS) GLONASS and GPS, as well as signals of ground and air radio navigation systems functionally similar to them. Method of controlling spatial coordinates geometry of node points of large objects is carried out using navigation radio signals of satellite radio navigation systems (SRNS) GLONASS and GPS, as well as signals of systems functionally similar to them, by installing in these points sensors position – antennas of radio-navigation navigation equipment, which determines their coordinates relative to sources of navigation signal (which makes it possible to monitor their mutual arrangement). Determination of relative coordinates by signals of SRNS is carried out by measuring the phase difference of carrier waveform of navigation spacecraft (NSC) signal, received by space-spaced antennae installed in control point mesh points, with connected to them radio-aided navigation equipment. Such phase difference is measured by high-accuracy navigation equipment with high accuracy and enables to determine signal path difference between antennas. Proceeding from such measurements, radio-orbital navigation equipment determines spatial orientation of antennae and recalculates it into spatial orientation of object, on which they are installed.

EFFECT: high accuracy of measuring the position of nodal points of large objects and providing continuous monitoring of their geometry.
