PITCH-ROLL BUOY WITH INERTIAL MEASURING UNIT BASED ON MICROMECHANICAL SENSORS Russian patent published in 2017 - IPC B63B22/00 G01C13/00 G01W1/04 

FIELD: measuring equipment.

SUBSTANCE: pitch-roll buoy comprises of a body providing the necessary buoyancy, a sealed compartment, at the bottom of which there is a rechargeable battery pack. The rechargeable battery pack is connected to an inertial measuring unit, a processing unit and an antenna located on the lid of the hermetic compartment. The inertial measuring unit is connected to the processing unit, which in turn is connected to an antenna. In the inertial measuring unit there are three micromechanical silicon vibration gyroscope, three micromechanical silicon accelerometers and a three-component magnetometer. The sensor sensitivity axes are directed orthogonally.

EFFECT: increasing the reliability of the pitch-roll buoy, increasing its autonomy, expanding the range of measured wavelengths, reducing the mass-dimensional characteristics of the buoy, increasing its vibration and shock resistance.
