Aerospace Instrument-Making Annotation << Back Selection calibration programs of the SINS accelerometer unit for the accounting of the square-size comparisons of scale factors Egorov Yu.G., Dzuev A.A. The problem of synthesizing calibration programs for the accelerometer assembly is considered. The criteria for the synthesis of optimal calibration programs for accelerometers are formed. An optimal program for accelerometer calibration from 18 measuring positions was synthesized and its accuracy characteristics were investigated. A mathematical model of the process of invariant calibration of accelerometers is presented, taking into account the quadratic components of the scale factor errors. The program for calibrating the accelerometer block was synthesized taking into account the quadratic components of the scale factor errors and its accuracy characteristics were investigated. Key words: accelerometer, strapdown inertial navigation system, invariant calibration, synthesis ofoptimal calibration programs.
