INTERNAL INSTRUMENT Russian patent published in 2007 - IPC G01C21/00 G01C19/72 G01P15/08 

FIELD: orientation and navigation instruments of movable objectives.

SUBSTANCE: the inertial instrument has a gyroscope and an accelerometer installed on a hollow shaft that has ball bearing supports, rotor of the synchronous motor, raster of the optical position sensor installed on a hollow shaft, stator of the synchronous motor, radiator and a light detector of the optical position sensor installed on the instrument body. Pairs of square beams serve as the sensitive elements of the gyroscope and accelerometer, the width of the beams is essentially larger than the height, they are attached to the shaft perpendicularly to the axis of rotation in such a manner that the wider side of the beam for the gyroscope lies in the plane perpendicular to the shaft axis of rotation, and for the accelerometer the narrower side of the beam lies in the plane perpendicular to the shaft axis of rotation. The instrument also comprises two pairs of beams and two rims, the shape of additional pair of beams for the gyroscope is similar to those already available and installed on the shaft perpendicularly to those already available in such a manner that the longitudinal axes of all four beams lie in the same plane, and the narrower sides of the additional beams lie in the plane perpendicular to the axis of rotation, rigidly coupled to the gyroscope beams is rim representing a hollow cylinder, whose height equals the beam width, the additional pair of beams for the accelerometer is similar in shape to the already available ones and installed on the shaft in parallel-succession with the already available ones at a distance equal to the beam width, rigidly coupled to the accelerometer beams is a rim representing a hollow cylinder, whose height is equal to the triple width of the beam.

EFFECT: enhanced sensitivity of the instrument.
