GuideNav’s FOG-based inertial measurement units (IMUs) are built for applications demanding precise navigation and long-term stability, including unmanned systems operating in dynamic or GPS-denied environments. These IMUs provide highly accurate angular rate and acceleration data, making them ideal for aerospace, defense, and industrial platforms that rely on dependable inertial navigation.
The product line spans from the compact GFIMU400 to the ultra-high precision GFIMU120, delivering bias stability down to 0.005°/h and angular random walk as low as 0.003 m/s/√hr. With rate ranges up to ±500 °/s and weights under 5 kg, GuideNav’s FOG IMUs are optimized for integration into unmanned aerial, ground, and maritime systems requiring consistent, high-performance inertial data.
