The LKF-MSU104 MEMS Inertial Measurement Unit is a highly reliable, cost-effective six-axis MEMS IMU designed for a wide range of applications including navigation, control, and measurement in vehicles, ships, and unmanned aerial vehicles.
The MSU104 series IMUs integrate high-performance MEMS gyroscopes and MEMS accelerometers within an independent structure. The selected gyroscopes and accelerometers represent the leading edge of MEMS-based inertial device technology. The system compensates for angular motion of the three-axis MEMS gyroscope's sensitive carrier and linear acceleration of the three-axis MEMS accelerometer's sensitive carrier for zero offset, scale factor, non-orthogonality error, and acceleration-related terms across the entire temperature range, ensuring high measurement accuracy over extended periods.
The MSU104 series of inertial measurement modules can be customized with different hardware and software configurations to meet specific user requirements.
