ROLL ANGLE SENSOR FOR ROTATING OBJECT Russian patent published in 2024 - IPC G01C21/18 G01C19/56 

FIELD: measuring instruments.

SUBSTANCE: invention relates to gyroscopic devices used in information-measuring systems for orienting rotating objects and controlling their movement. The essence of the invention is as follows. The design of the roll angle sensor for a rotating object includes two channels, two cross connections between them, and an auxiliary frequency generator. The first channel is implemented from the first device for measuring accelerations to the first computer through the first binary multiplier and the first reversible binary counter connected in series through the information inputs. The second channel is implemented from the second device for measuring acceleration to the second computer through the sixth binary multiplier and the second reversible binary counter connected in series through the information inputs. The first cross-coupling is implemented from the output of the first reversing binary counter of the first channel to the input of the second reversing binary counter of the second channel through the second and third binary multipliers connected in series along the information inputs. The second cross-coupling is implemented from the output of the second reversing binary counter of the second channel to the input of the first reversing binary counter of the first channel through the fourth and the fifth binary multipliers connected in series along the information inputs. The third and the fifth binary multipliers are connected to a device for measuring angular velocity, and the inputs of the first, the second, the fourth, and the sixth binary multipliers are connected to the output of the auxiliary frequency generator. The outputs from the first and the second computers are discrete outputs of the roll angle sensor for a rotating object.

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