An upgraded version for KIND34-040. The small-size device for measuring the angular velocity is designed to measure the integrals of the absolute angular velocity vector projections of the spacecraft when operating in the orbital section of the spacecraft as part of the spacecraft control system. The instrument is designed as a free-form inertial block, which uses small sensitive elements of DNG type. The device provides operation in rough and precise operation modes. Rough mode allows to carry out measurements with less accuracy, but in a larger range immediately after switching on the IR. The device has 6 measuring channels, the sensitivity axes of which are located in pairs along the axes of the orthogonal coordinate system. The failure of any of the IR (DNG) of the device does not affect the purposes of its intended use.
