Late last century (1982) a team of DELCO specialists (USA) working under the guidance of David Lynch developed and presented to the international community an industrial prototype of a brand new type of gyroscope - hemispherical resonator gyro (HRG). In contrast to all the above mentioned gyroscopes a HRG is based on a brand new physical phenomenon (Brayan effect) – preservation of inertial properties in standing waves generated at the edge of a hemispherical resonator. Depending on the method employed to control the standing wave the instrument may be operated in two modes: as an angle sensor (integrating gyro) or as an angular velocity sensor (AVS).
