DINAMIC CALIBRATION OF THE TRIAD OF ACCELEROMETERS ON THE TWO-AXIS BED

Consider dynamic calibration mode of micromechanical accelerometers. The acceleration caused by oscillation of micromechanical accelerometers round the center of the bed is studied. The proposed algorithm makes it possible to determine not only the coefficients of mathematic model of micromechanical accelerometer error but also the location of the triad in closed cover of inertial measurement unit. Results of calibration of micromechanical accelerometers in the two-axis bed are presented.
