FIELD: measurement equipment.
SUBSTANCE: method of estimating the errors of systematic drift triaxial gyroscope, which consists in taking measurements of output signals of a triaxial gyroscope in several azimuthal positions and digital processing of the measurements, characterized in that the measurement of several azimuthal positions make when turning base triaxial gyroscope around a vertical axis, a digital measurement processing carried out by the construction of approximating functions and definitions of approximation coefficients, calculating the constant projection of the vertical component of the Earth's angular velocity, taking into account the constructive position of the axes of sensitivity, determining the difference between the obtained approximation coefficients and the estimated value of the projection of the vertical component of the angular velocity of the Earth on the gyroscope sensitivity axis.
EFFECT: increase the accuracy characteristics of a three-axis gyroscope by increasing the reliability of the evaluation of systematic errors triaxial gyroscope, while reducing the complexity of the measurement process.
