LKF-SX-MG300K Waterproof MEMS North Finder for Navigation
Liocrebif's LKF-SX-MG300K MEMS north finder is a highly reliable, cost-effective six-axis MEMS inertial unit integrating high-performance three-axis gyroscopes and accelerometers to measure angular and linear motion. Full-temperature bias, scale factor, non-orthogonality, and acceleration-related compensation—combined with high-speed sampling and fine static/dynamic correction—maintains high measurement accuracy over extended operation. Vibration-isolated and sealed, it operates stably in harsh environments, delivering a low-cost, high-reliability solution with customizable precision and flexible hardware/software configurations for inertial navigation, attitude stabilization, and measurement applications.
