FIELD: aircraft equipment. SUBSTANCE: device uses gyro integrators which are located on stabilized platform. Device provides possibility to detect velocity vector in arbitrary point of aircraft by means of aircraft angular movement using orientation detector, angular velocity vector detector, device which calculates mapping of projection of vector in inertial coordinate system to projections to bound axes, as well as unit which maps vector from projection to bound axes to projection in inertial coordinate system. Values at output of velocity vector detector are converted to accelerations in bound coordinate system by means of linear velocity processing unit, velocity vector multiplication unit and acceleration vector calculation unit which output provides output signals of first group of information outputs of system. Output signals of second group of information outputs of system are generated by unit which calculates velocity vector by means of addition of velocity values caused by reciprocal and rotational movement of aircraft. Aircraft point for investigation by system is chosen by setting concrete values in setter of measuring point coordinates. EFFECT: simultaneous calculation of velocity and acceleration vectors in arbitrary sections of aircraft. 2 cl, 7 dwg
