METHOD FOR CALIBRATING DINAMICALLY ADJUSTABLE GYROSCOPE AS PART OF INERTIAL NAVIGATION SYSTEM Russian patent published in 2021 - IPC G01C21/00 

FIELD: instrument engineering.

SUBSTANCE: invention relates to instrument engineering and can be used for calibrating the time-changing angular velocity of dynamically adjustable gyroscopes as part of an inertial navigation system and the errors thereof in the development of orientation and navigation parameters, caused by said velocity of drift. In order to calibrate the time-changing angular drift velocity of dynamically adjustable gyroscopes as part of the inertial navigation system and the error in its orientation and navigation parameters caused by said drift velocity, the inertial navigation system is first installed on a horizontal fixed base relative to the ground, its launch is carried out, the gyroplatform is installed on a horizontal plane and on the plane of the meridian. Furthermore, a stabilized platform with dynamically adjustable gyroscopes is held in this spatial position, the signals of settings ate delivered to the inlet of on-course gyroscope stabilization channel amplifier, of electric spring amplifier of the channel as well as of the amplifiers for stabilizing the channels of roll and tangage. The time changes of orientation and navigation parameters produced by the inertial navigation system are then measured. Other launches are carried out with other settings, the results of which are used to detect signals of settings minimizing errors in the development of inertial navigation system parameters for orientation and navigation and in the operating modes signals formed in the computer on the basis of these minimizing settings are delivered into the channels for stabilizing the gyroplatform and into the channel of the electric spring of the course gyroscope.

EFFECT: technical result consists in ensuring adjustment of dynamically adjustable gyroscopes as part of an inertial navigation system which enables reducing the monotone change in the gas-dynamic drift velocity of dynamically adjustable gyroscopes and the resulting errors in the inertial navigation system by the development of the orientation and navigation parameters without replacing the gyroscope in the system.
