STRAPDOWN INERTIAL VERTICAL ON "ROUGH" SENSITIVE ELEMENTS Russian patent published in 2017 - IPC G01C21/16 

Abstract RU 2615033 C1

FIELD: physics.

SUBSTANCE: three-channel unit of the micromechanical linear acceleration sensors (error up to 0.05 m/s2) is used, and a three-channel unit of the micromechanical angular rate sensors (accuracy to 0.2°/c) is used with high performance without the use of external adjustment. This provides the automatic starting and heading exhibition of the vertical, the error write-off of the angular velocity sensors directly before the flight and the periodic correction of the angular velocity sensors during the flight, as well as the use of the quaternion calculations.

EFFECT: construction of the all-power microminiature strapdown inertial vertical on the rough sensitive elements.
