MEMS Inertial Measurement Unit (MEMS IMU)

MU8008

Advanced Process & Technology

The MU8008 MEMS inertial measurement module is a highly reliable, cost-effective six-axis MEMS inertial sensor, widely applicable to navigation, control and measurement scenarios such as vehicles, ships and UAVs. It integrates high-performance MEMS gyroscopes and accelerometers (both representing leading levels of MEMS inertial devices) in an independent structure: the 3-axis MEMS gyroscope detects the angular motion of the carrier, while the 3-axis MEMS accelerometer senses linear acceleration. The system incorporates full-temperature parameter compensation (for zero offset, scale factor, non-orthogonal error, etc.), enabling long-term high measurement accuracy.
 

High-Precision Device Manufacturing & System Calibration Compensation Technology

The company has accumulated a series of key technologies during R&D to ensure the product’s high performance. Meanwhile, the system adopts high-speed sampling, full-temperature static error compensation (for zero offset, installation error, etc.), and dynamic error compensation technologies, ensuring optimal performance during user operation.
