DEVICE FOR DETERMINING ASTRONOMICAL AZIMUTH Russian patent published in 2023 - IPC G01C21/24 

FIELD: measuring equipment.

SUBSTANCE: optical-mechanical measuring device for astronomical and geodetic purposes that can be used for high-precision determination of the astronomical azimuth of a given direction, necessary for testing and configuring mobile devices used in solving navigation problems. The device for measuring the astronomical azimuth contains a computing device, an autocollimator sight, a highly sensitive television camera of which is synchronized with an accurate time sensor, and control module element optically coupled to the autocollimator sight with a biaxial horizon sensor mounted on it. At the same time, a mark transfer lens is used as part of the autocollimator sight, and the control element module is made of a rigidly connected sighting prism, the angle of inclination of which is invariant with respect to the latitude of the location, and a two-sided vertical mirror having central holes of different diameters coaxial with the optical axis of the lens.

EFFECT: increased accuracy and efficiency of determining the astronomical azimuth, as well as standardization when using the device at different latitudes.
