ANGULAR VELOCITY MEASUREMENT METHOD Russian patent published in 2010 - IPC G01P3/44 

FIELD: measurement equipment.

SUBSTANCE: invention relates to orientation, navigation and control of moving objects and is intended for angular velocity measurement. The angular velocity measurement method consists in measurement of the change in acoustic wave characteristics in presence of rotation. The informative signal is represented by the value of change in polarisation of a crosswise voluminal acoustic wave. To the radiating transducer a signal is transmitted in the form of a sequence of radio pulses whose length does not exceed the doubled time of acoustic wave propagation in the acoustic line. The orthogonal component of the crosswise voluminal acoustic wave under study that is generated due to impact of Coriolis force is registered with the receiving transducer. The signal occurring thereby is proportional to rotation velocity.

EFFECT: improved sensibility of the method for measurement of angular velocity as well as its design implementation simplification.
