Product Description
LKF-FSI400 FOG/GNSS Combined Inertial Navigation System
Product Overview

FSI400 is a highly reliable, cost-effective fiber-optic inertial/satellite integrated navigation system, widely applicable in fields such as high-precision vehicle-mounted platforms and long-endurance UAVs, as well as navigation, control, and measurement.

The system uses closed-loop fiber optic gyroscopes (FOG) and high-precision accelerometers, combined with a professional GNSS board, to achieve real-time navigation output. The system output is compatible with mainstream post-processing software to obtain higher-precision navigation results and serve as a benchmark for research platforms.
