ROLL ANGLE SENSOR FOR ROTATING OBJECT Russian patent published in 2024 - IPC G01C21/00 

FIELD: physics.

SUBSTANCE: invention is intended for use as an element in stabilization and navigation systems. Roll angle sensor for a rotating object has devices for measuring accelerations, the sensitivity axes of which are mutually orthogonal and perpendicular to the longitudinal axis of rotation of the object, an angular velocity sensor, two channels and two cross-links. First channel is implemented from the first digital device for measuring accelerations to the first digital information to direct code converter through connected in series via the information inputs the first binary multiplier, first reversible binary counter, final register of the first reversible binary counter. Second channel is implemented from the second digital device for measuring accelerations to the second digital information to direct code converter through connected in series on the information inputs the sixth binary multiplier, the second reverse binary counter, final register of the second reversible binary counter. In addition, one cross-coupling is implemented from the output of the first reverse binary counter to the input of the second reverse binary counter of the second channel through the second and third binary multipliers, second cross-coupling is implemented from the output of the second reverse binary counter to the input of the first reverse binary counter of the first channel through the fourth and fifth binary multipliers.

EFFECT: high accuracy of measuring the roll angle of a rotating object.
