Rugged High-Speed FOG for Demanding Unmanned Applications

G321M Fiber Optic Gyro

The G321M is a precision-engineered 3-axis fiber optic gyroscope (FOG) designed to deliver uncompromising angular rate data in high-dynamic unmanned environments. Compact, lightweight, and built to endure extreme operational stressors, it is ideal for integration into UAVs, UGVs, autonomous maritime systems, and other robotic platforms operating in harsh tactical theaters.

Constructed with an aerospace-grade aluminum alloy chassis, the G321M provides exceptional resilience to thermal fluctuation, high-frequency vibration, and impact shock. The unit supports operating temperatures from -40°C to +70°C, with survival capabilities extending from -55°C to +85°C, ensuring reliable function across arctic and desert conditions alike. Engineered to withstand 6g RMS vibration and mechanical shocks up to 350g, the G321M is well-suited for both ground and aerial deployments in austere environments.

The system offers a 400°/s input range with a high 1kHz bandwidth, making it ideal for applications requiring low-latency inertial data in rapid maneuvering scenarios. Delivering angular rate measurements at up to 8kHz, the G321M supports real-time control and stabilization for advanced guidance, navigation, and control (GNC) systems.

Weighing just 145 grams (0.3 lb) and housed within a 53 x 53 x 36 mm enclosure, the G321M delivers superior inertial performance without compromising payload weight or space. Consuming only 2 watts, it is optimized for integration into platforms where Size, Weight, and Power (SWaP) constraints are critical.

The G321M is a tactical-grade fiber optic gyroscope developed to meet the rigorous demands of unmanned systems operating in unpredictable conditions. Its robust construction, high data fidelity, and fast response time make it a core component for precise inertial navigation in autonomous and remotely piloted missions.
