The CRH03 is a single-axis MEMS gyroscope that outputs high-accuracy angular velocity data with comparable bias characteristics to bulkier and more expensive FOG- and DTG-based sensors. Based on Silicon Sensing's unique resonating ring gyroscope technology, the gyro features low noise and incorporates a built-in temperature sensor that allows the unit to be precisely configured according to changes in environmental conditions.

The CRH03 is available in five dynamic ranges, and can be provided as an OEM board or in a robust enclosure. OEM boards are also offered in three different frequency variants to suit multi-axis applications. The versatile sensor is ideal for maritime platform guidance, stabilization and control.
