The paper is devoted to solving the problem of calibration with specified precision of triaxial block of navigation accelerometers on the uniaxial rotary stand.In paper introduced all the characteristics, for calibration of triaxial block of navigation accelerometers on the uniaxial rotary stand, instrumental error sources upon which was obtained mathematical errors model of calibration. This model allows to calculate the error which the coefficients of metrology model of triaxial accelerometer unit was identified, if we have the numerical values of precision equipment errors.Using the mathematical errors model of calibration, and the quality criterion of calibration of triaxial block of navigation accelerometers unit, were obtained inequality that used to determine requirements for accuracy characteristics bench equipment, on which the calibration is performed. These requirements ensure the calibration of triaxial block of navigation accelerometers on the uniaxial rotary stand with preset accuracy.Experimental verification was conducted on comparable accuracy errors existing equipment and the requirements to this equipment , confirm the adequacy of the obtained inequalities.As the result of research were identified the most influential sources of instrumental errors, and provided recommendations to reduce their impacts.
