METHOD FOR COMPENSATING ERRORS OF NAVIGATION INFORMATION COMPLEX AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2023 - IPC G01C21/10 G01C19/58 

FIELD: navigation measurements.

SUBSTANCE: determination of the coordinates of the moving object location, such as an aircraft (AC). The method for compensating errors in the navigation information complex consists in rotating an inertial measuring unit consisting of an accelerometer unit and a laser gyroscope unit and fixed on the rotation mechanism, obtaining information about the angular velocity and AC acceleration in the units of laser gyroscopes and accelerometers, transmitting data on the angular velocity and AC acceleration into a digital microprocessor. The microprocessor calculates the AC orientation angles and its coordinates, then refines the control law of the inertial measuring unit, taking into account the statistical characteristics of the gyroscope drift and accelerometer errors. In this case, the AC angular velocity is measured by an additional gyroscope, the signal from which is fed to a digital microprocessor to calculate the AC orientation angles and its coordinates. Refinement of the control law of the inertial measuring unit is additionally carried out on the basis of information provided by the gyroscope drift set unit and the set unit for determining the parameters of the misalignment of the gyroscope sensitivity axes, the signals from which are fed to the control law determination unit to calculate the value of the required angular velocity of the inertial measuring unit.

EFFECT: increase in the accuracy of determining the flight and navigation parameters of the aircraft flight.
