Error Analysis Technique for Indirect Method of Calibration of a Strapdown Inertial Measurement Unit

Possible versions of the indirect method of calibration of a strapdown inertial measurement unit are briefly analyzed. The version of the indirect method with simple measurement equations that can be decomposed and solved just algebraically is considered. The technique for obtaining analytical expressions connecting calibration errors with their sourced and expressions themselves are described. The influence of the calibrated parameters, uncalibrated parameters, and errors of calibration equipment on the calibration accuracy is analyzed.
