METHOD OF DETERMINATION OF TEMPERATURE DEPENDENCES OF SCALING FACTORS, ZERO SHIFTS AND ARRAY OF ORIENTATION OF AXES OF SENSITIVITY OF LASER GYROSCOPES AND PENDULUM ACCELEROMETERS AS PART OF INERTIAL MEASURING UNIT AT BENCH TESTS Russian patent published in 2015 - IPC G01C25/00 

Abstract RU 2566427 C1

FIELD: instrument making.

SUBSTANCE: invention can be used for determination of temperature dependences of characteristics of the three-axis laser gyroscope (LG) and the pendulum accelerometers (PA) as a part of the inertial measuring units (IMU). At the stand IMU with three-axis LG and three PAs, fitted with rotation sensors, at each step of measurements the amount of impulses for each of three LG rotation sensors is determined which is proportional to the projection of LG rotation angle vector per one step of measurements per each of three axes of LG sensitivity, averages per one step of measurements of values of voltage at the output of three PAs proportional to projections of the vector of imaginary linear acceleration to the axes of sensitivity of PAs , and averages per one step of measurements of temperature in each of three rotation sensors of three-axis LG and three PAs are determined, using which the temperature dependences of all scaling factors of LG and PA are determined.

EFFECT: expansion of functional capabilities.
