Abstract
The technique for calibration of sensors in a strapdown inertial measurement unit on a relatively coarse (1°–2°) turntable are discussed. The proposed technique is based both on direct and indirect methods. Calibration errors are estimated analytically and, also, by means of mathematical simulation. For direct methods, the choice of program orientations is substantiated; the vector method is compared with the scalar one. The results of calibration of a measurement unit on fiber-optic gyroscopes obtained with the use of the proposed technique are given.中文翻译:
