Abstract
A new calibration method of triaxial navigation accelerometer unit on uniaxial rotary stand is considered.The aim is to determine the model of coefficients identification of metrology model for triaxial accelerometer unit by the method mentioned above.Metrology model of triaxial navigation accelerometer unit as a vector transmitter, physical and mathematical foundations of a new method for its calibration are described.To ensure the identifiability of all coefficients of the metrological model, two installations of accelerometer unit on a platform of uniaxial rotary stand were introduced. Identification models for metrology model of triaxial accelerometer unit were produced.Experimental validation of the obtained identification coefficients models was carried out. The ability to calibrate a triaxial accelerometer navigation unit with the given accuracy was confirmed.According to the research specific recommendations for the practical application of the developed calibration method are proposed.
