CRH02 Gyroscoop

Compact, high performance single axis gyroscope, providing outstanding stability with low noise

About the CRH02 Gyroscope 

CRH02 provides the optimum solution for applications where bias instability, angle random walk and low noise are of critical importance.
At the heart of the CRH02 is Silicon Sensing’s VSG3Q MAX vibrating ring MEMS sensor which is at the pinnacle  of 15 years of design evolution and the latest off a  line which has produced over 30 million high integrity  MEMS inertial sensors. The VSG3Q MAX gyro sensor  is combined with precision discrete electronics to  achieve high stability and low noise, making the  CRH02 a viable alternative to Fibre-Optic Gyro (FOG)  and Dynamically Tuned Gyro (DTG).
An on board temperature sensor and the resonant  frequency of the MEMS enables additional external  conditioning to be applied to the CRH02 by the host,  enhancing the performance even further.
Typical applications include downhole surveying,  drilling equipment, precision platform stabilization,  ship stabilisation, ship guidance and control,  autonomous vehicles, high-end AHRS and other  flight in-struments.
Whatever your application, the unique and patented silicon ring technology gives advanced and stable performance over time and temperature, overcoming mount sensitivity problems associated with simple beam or tuning fork based sensors.
