Metrology model of triaxial navigation accelerometer unit as a vector transmitter, physical and mathematical foundations of a new method for its calibration on uniaxial rotary stand are considered. The aim is to determine the coefficients of metrology model for triaxial accelerometer unit by the method mentioned above. 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.
