Calibration of inertial sensors is one of the most important tasks in the development of inertial navigation systems. The solution to this problem is impossible without achieving the required level of accuracy of dynamic modeling test-benches used in their development. The paper describes a technique of constructing a measuring base for determining the azimuthal attitude of the precision dynamic test-bench. This techniques used industrial geodesy technologies for providing ability to calibrate all major types of modern inertial measuring units in a wide temperature range. The azimuthal attitude determining is based on measuring the angular attitude of the mirror placed on the test-bench’s turntable by an autocollimation measurements technique by using a high-precision reflectorless total station, the coordinates of which are determined by rangefinder-goniometric measurements to reflectors with known coordinates, mounted on the room’s walls. The calculation results shows that proposed technique of constructing a measuring base allows to ensure the measurement accuracy for carrying out research and calibration of highly accuracy inertial measuring systems.
