FIELD: measuring.
SUBSTANCE: invention relates to measurement equipment, namely to measurement of motion parameters of an object and can be used in strapdown inertial navigation systems. Angular velocity vector of the object is determined from the measured three angular velocity components directed along the axes of sensitivity of the three two-degree gyroscopic angular velocity sensors. Technical solution is aimed at reducing the error from non-commutativity of final turns of the object.
EFFECT: high accuracy of measuring motion parameters owing to compensation for errors caused by angular acceleration of the object, and simplifying the design.
