INERTIAL GAUGE OF AIRCRAFT ON MICROMECHANICAL SENSORS AND METHOD OF IMPROVING ACCURACY THEREOF Russian patent published in 2017 - IPC G01C21/00 

FIELD: physics, instrument-making.

SUBSTANCE: invention relates to instrument-making, particularly to inertial information measurement devices, and can be used in orientation and navigation systems of mobile objects. An inertial gauge of aircraft further includes a device for synchronising output information on inertial sensors, a device for determining the zero signal of micromechanical gyroscopes from acceleration, and a shock absorber platform on which is installed a module of sensitive elements, structurally made in the form of a rigid monolithic support arm, in the base of which are installed shock absorbers, wherein the pass band of the shock absorbers is much smaller than the pass band of micromechanical gyroscopes and accelerometers, installed on the shock absorber platform, and much lower than the natural vibration frequency of the sensitive elements of the micromechanical gyroscopes and accelerometers installed on the shock absorber platform.

EFFECT: high accuracy of the inertial gauge of aircraft and broader functional capabilities thereof.
