The LKF-MSI105 MEMS Inertial Navigation System is a compact, cost-effective solution designed for navigation, control, and measurement applications, particularly for drones and other mobile platforms.
This integrated navigation system combines a GNSS satellite receiver and information processing functions on a single chip with a built-in IMU. It captures real-time angular rate and acceleration data while receiving GNSS satellite signals from dual antennas or track angles, computing heading angle, three-dimensional velocity, position, and attitude information.
The system features full-temperature zero-point and scale compensation for the internal IMU module, ensuring reliable performance. Based on receiver functionality, it maintains positioning accuracy during short-term satellite outages and attitude accuracy during medium to long-term satellite outages.
