    AI Overview
    Fiber Optic Gyroscope (FOG) and Global Navigation Satellite System (GNSS) hybrid navigation systems combine high-precision inertial sensors with satellite positioning to deliver accurate, reliable, and continuous navigation. FOG-based Inertial Navigation Systems (INS) provide exceptional accuracy in orientation and velocity, operating continuously even during GNSS outages, jamming, or spoofing, which makes them ideal for autonomous vehicles and unmanned systems. 
    Key Features and Benefits 
    • High Performance: FOGs offer superior precision in rotation measurement, essential for reliable heading.
    • Robustness in GNSS-Denied Areas: When satellites are blocked or signals are jammed, the FOG-INS component uses dead reckoning to maintain high-accuracy navigation for extended periods.
    • Optimal Sensor Fusion: Advanced, AI-based fusion algorithms (like those in) blend high-accuracy, low-drift FOG data with RTK GNSS, accelerating and refining, for example, self-north finding to

      .
    • Redundancy: Systems often include extra sensors, such as MEMS IMUs for backup, accelerometers, magnetometers, and pressure sensors for enhanced reliability.
