Certification:
GJB 9001C-2017
Model Number:
LKF-MSU203
The LKF-MSU203 MEMS Inertial Measurement Unit (IMU) is a highly reliable and cost-effective six-axis MEMS inertial measurement module, widely applicable in navigation, control, and measurement fields such as vehicles, ships, and UAVs. The LKF-MG209A series integrates high-performance MEMS gyroscopes and accelerometers within an independent structure, with selected components representing the leading edge of MEMS-based inertial technology. All electronic components are 100% domestically sourced.
The triaxial MEMS gyroscopes detect angular motion of the carrier, while the triaxial MEMS accelerometers measure linear acceleration. The system incorporates comprehensive temperature compensation for zero bias, scale factor, non-orthogonal errors, and acceleration-related terms, ensuring sustained high measurement accuracy over extended periods.
The LKF-MSU203 series supports customizable hardware and software configurations to meet diverse user requirements. For specific navigation applications, the gyroscopes can be upgraded to high-precision MEMS models, maximizing adaptability to varying needs.
High quality and reliability
The company can effectively improve product quality and reduce system costs by comprehensively controlling upstream and downstream processes and technologies. At the same time, the company implements ISO9001 and GJB quality systems, and adopts strict processes to ensure the reliability and consistency of product performance.
