LKF-MSU300 High-Precision MEMS Inertial Measurement Unit (IMU) is a highly reliable and cost-effective six-axis MEMS inertial sensor module, designed for a broad range of navigation, control, and measurement applications—particularly in inertial navigation and attitude stabilization.
LKF-MSU300 supports custom hardware/software configurations to meet diverse user requirements. For specialized inertial navigation applications, the gyroscope can be upgraded to high-precision or high-dynamic MEMS gyros, ensuring optimal performance for different operational needs.
LKF-MSU300 IMU integrates high-performance MEMS gyroscopes and accelerometers within a standalone structure. The selected gyroscopes and accelerometers represent the leading edge of MEMS inertial technology, with 100% domestically sourced electronic components.
High-Precision Manufacturing /System Calibration Technology
The company has developed a series of key technologies during the R&D process to ensure the product's high performance. The system employs high-speed sampling, static error compensation (fine compensation for zero bias, scale factor, and misalignment across the full temperature range), and dynamic error compensation (e.g., coning and sculling errors) to deliver optimal performance in user applications.
