Abstract
The influence of mobility of an inertial measurement unit (IMU) installed on shock absorbers on the accuracy of gyroscope calibration in strapdown inertial navigation systems (SINS) is discussed and the problem of its estimation considered. Based on the data obtained in calibration experiments, the IMU angular deviations are estimated using the algebraic form of the least squares method. A mathematical model of the IMU motion is constructed taking into account its relative mobility. The influence of this mobility on the calibration accuracy of gyroscopes is estimated.
