As an OEM sensor, the CRH03 (OEM) is deliberately designed without a housing and is aimed at developers and system integrators who require maximum design flexibility. Its open design enables optimal integration into customer-specific systems, such as inertial measurement units or complex control solutions. This allows the sensor to be precisely adapted to mechanical, thermal and electronic requirements, making it ideal for series applications with the highest performance demands.
With the CRH03 (OEM), Althen presents a high-precision rate sensor that combines the performance of traditional high-end gyroscopes with the advantages of modern MEMS technology. Thanks to its innovative silicon ring structure, the sensor offers exceptionally low bias instability, minimal noise and high robustness against temperature and vibration effects — while maintaining a compact and cost-efficient design.
Applications for the CRH03
The CRH03 (OEM) was specifically developed for demanding applications where precise and long-term stable angular rate measurements are required. In inertial measurement units (IMUs) and AHRS systems, it enables precise determination of attitude, orientation and heading — even without continuous GNSS support. In aerospace applications and UAVs, it ensures reliable flight attitude stabilisation and navigation, even under strong vibrations and changing environmental conditions. In robotics and autonomous vehicles, the sensor contributes to accurate motion control, lane keeping and obstacle navigation.
The CRH03 (OEM) is also ideal for maritime applications such as gyrocompassing and platform stabilisation, where long-term drift stability is essential. In surveying technology, it supports highly accurate attitude and direction measurements, for example in mobile mapping systems or drilling applications. The sensor also provides clear added value in industrial and safety-critical areas — such as railway monitoring or stabilised camera platforms — thanks to its combination of precision, robustness and long-term stability.
