Fiber Optic Integrated Navigation System
A fiber optic integrated navigation system is a comprehensive platform combining fiber optic gyroscopes, accelerometers, and GPS/GNSS integration enabling precise three-dimensional positioning and inertial navigation. The integrated system approach provides continuous autonomous navigation capability during GPS denial or RF jamming enabling military and civilian navigation applications.
The fiber optic integrated navigation system architecture combines multiple sensor modalities. Fiber optic gyroscopes measure angular rotation rate enabling heading determination. Fibre optic accelerometers measure linear acceleration enabling velocity and position computation. GPS/GNSS receivers provide absolute position reference correcting accumulated inertial navigation errors. Sensor fusion algorithms blend measurements providing optimal position and attitude estimates.
Operational specifications include position accuracy typically 1–10 metres depending on GPS availability and inertial sensor quality, heading accuracy typically ±2–5 degrees enabling navigational control, and autonomous navigation capability spanning hours to days without GPS enabling operation during jamming or denial. Real-time attitude measurement enables platform stabilisation and targeting.
Deployment applications include aircraft navigation providing dead-reckoning capability during radio silence, marine vessel guidance enabling precise course control and collision avoidance, land vehicle navigation enabling autonomous operation across GPS-denied terrain, and missile guidance providing precise targeting information. Integrated approach eliminates dependency on single sensor reducing vulnerability to jamming.
Environmental operation across -40°C to +85°C temperature ranges supports deployment across diverse settings. Rugged construction enables operation across mechanical stress typical of vehicle platforms.
