About the CRH03 (OEM) Gyroscope

The CRH03 (OEM) is a high-precision analog rate sensor (MEMS gyroscope) designed for demanding applications where low bias instability, minimal noise, and high measurement accuracy are critical.

The sensing element is based on an advanced vibrating silicon ring structure (MEMS technology), which provides exceptional stability against temperature variations, vibration, and aging effects. This enables performance comparable to fiber optic gyroscopes, but in a significantly more compact and cost-efficient design.

The CRH03 (OEM) delivers a precise analog output signal for measuring angular rates and is optimized for use in highly dynamic and safety-critical systems. An integrated temperature sensor and advanced compensation capabilities ensure stable performance across a wide temperature range.

  • High-precision MEMS rate sensor with analog output
  • Very low bias instability (typ. ~0.04°/h at 100°/s)
  • Excellent angular noise values (Angle Random Walk approx. 0.006°/√h)
  • Low noise and high signal stability
  • Multiple measurement ranges available (e.g. ±100°/s depending on variant)
  • Integrated temperature sensor for enhanced compensation
  • High shock and vibration resistance
  • Compact design with low power consumption (typ. 5 V supply)

Applications

  • Inertial navigation systems (INS / IMU)
  • Platform stabilization and control
  • Aerospace applications
  • Autonomous vehicles and robotics
  • Marine and offshore systems
  • Surveying and industrial precision systems

The CRH03 (OEM) combines the advantages of modern MEMS technology with performance typically associated with significantly more expensive gyroscope technologies. Its robustness, precision, and long-term stability make it ideal for professional use in harsh environments.
