The optimum high-performance unhoused MEMS gyroscope for applications where bias instability, angle random walk and low noise are of critical importance.

The CRH03 (OEM) is a class-leading standalone MEMS gyroscope. For endless applications, 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. It is a small, high-performing, robust MEMS gyro which is a viable and cost-effective alternative to Fibre Optic Gyro (FOG) and Dynamically Tuned Gyro (DTG).
