APPARATUS FOR DETERMINING SINGLE-ALTITUDE HIGH-ACCURACY GEODETIC REFERENCE DIRECTIONS IN FIELD CONDITIONS Russian patent published in 2022 - IPC G01C15/00 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the field of gyroscopic systems and can be used to determine the azimuth of a reference geodetic direction in field conditions with high accuracy by a gyroscopic method. Apparatus for determining single-altitude high-accuracy geodetic reference directions in field conditions consists of a gyrotheodolite, a two-sided BR-180 prism, an upper appliance of a mobile object. Additionally introduced thereto are an apparatus for securing the gyrotheodolite installation appliance and a guide prism made in a single body with the two-way BR-180 prism, wherein the input of the two-way BR-180 prism is in direct and return connection with the gyrotheodolite, in turn, the output of the two-way BR-180 prism is in direct and return connection with the input of the upper appliance of the mobile object via the guide prism. The apparatus for securing the gyrotheodolite installation appliance is a stable support for the gyrotheodolite and is in direct connection therewith.

EFFECT: increase in the promptness of deploying the apparatus in a field area and minimisation of the impact of seismic effects on the appliance.
