BEFGA40ATactical Grade IMU Fiber Optic Navigator - Multi-Mode High-Precision UAV Navigation Solution
This small autonomous fiber optic navigator uses fiber optic gyroscopes and fiber optic star measurement sensors, combined with advanced navigation and star measurement control software, to provide multi-mode navigation solutions in real time. It has multiple working modes such as pure inertial, inertial/starlight combination, and inertial/satellite combination, and is suitable for medium and large long-flight manned and unmanned aircraft, ensuring high-precision positioning under satellite denial conditions.
