Marine Fiber Optic Gyroscope Sensor with 2 deg/h Bias Stability and ±500 deg/s Angular Rate for Ship Navigation
MFOG-24 Marine Fiber Optic Gyroscope Sensor 2 deg/h Bias for Ship Navigation and Gyrocompass Systems
The MFOG-24 is a marine-grade fiber optic gyroscope designed to provide reliable angular rate data for ship navigation and gyrocompass systems. Its solid-state construction withstands the continuous vibration and motion encountered in maritime environments.
Using the Sagnac effect, the MFOG-24 delivers consistent 2 deg/h bias stability without the maintenance requirements of mechanical gyrocompasses. The compact φ24×39mm form factor enables integration into space-constrained marine navigation consoles.
- Solid-state design eliminates mechanical gyrocompass maintenance
- Angular rate range: ±500 deg/s, zero-bias stability ≤2 deg/h (1 sigma)
- 20g vibration resistance for continuous marine vessel operation
- Operating temperature: -40 to +65°C for all-weather maritime use
- Rapid start-up with no settling time versus traditional gyrocompass
- Analog output compatible with standard marine navigation electronics
