COMPENSATION FOR ERRORS OF INERTIAL MEASURING ELEMENTS AND DEVICE TO THIS END Russian patent published in 2015 - IPC G01C21/10 

FIELD: aircraft engineering.

SUBSTANCE: additional correction is performed for parameters of the law of control over inertial measuring unit on the basis of functional dependence of correction terms on aircraft flight duration. Proposed device comprises inertial measuring unit. The latter comprises unit of laser gyroscopes and unit of accelerometers, rotation mechanism, electronics unit of inertial measuring unit and interfaces, digital microprocessor, interface with navigation info, speed computer, data control and display unit, ADC and DAC, navigation info bus and correction unit. The latter incorporates: time counter, laser hydroscope error determination unit, correction signal output unit, control law parameters output unit, aircraft flight time master unit, control law parameters correction unit and adder unit.

EFFECT: higher control and navigation parameters.
