MEMS-based inertial sensor with digital SPI interface for GNSS positioning support

26-02-2021 | Murata | Test & Measurement

Murata has introduced a 6-DoF MEMS-based XYZ-axis inertial sensor for high-precision machine control and GNSS positioning support. The SCHA63T offers a digital SPI interface, allowing engineers to produce industrial equipment with sturdy and reliable, centimetre-level positioning accuracy, even in environments with high mechanical shock and vibration. Industrial applications the device is targeted are diverse and include IMUs, machine control and guidance equipment, navigation and positioning systems, dynamic inclination, robotic control, and UAVs.


The high-performance parameters of the sensor, such as gyro bias instability, which is down to the 1-degree/h level, and gyro noise density of 0.0015-degree/s/√Hz, allow the device to deliver best in class performance. The low acceleration linearity error assures high accuracy machine control and guidance. Cross-axis calibration facilitates better than 0.14-degree orthogonality error, saving system integrators precious development time and money on completing this process themselves. Extra features comprise user-selectable filter settings of 13/20/46/300Hz, and the extensive self-diagnostics allows it to be employed in safety-critical applications.
