. Key manufacturers include
EMCORE (formerly KVH/Systron Donner)
,
Honeywell
,
Northrop Grumman
,
Exail (iXblue)
,
Advanced Navigation
, and
MostaTech

Primary OEM FOG IMU Applications
- Unmanned Systems (UAVs, UGVs, UUVs): OEM FOG IMUs provide critical, high-stability, and low-noise data for flight control, navigation, and stabilization in drones and autonomous robots.
- Defense & Missile Guidance: Used for precision targeting, missile guidance systems, and weapon system stabilization.
- Aerospace & Aviation: Applied in attitude heading reference systems (AHRS) for manned aircraft, helicopters, and space vehicles/CubeSats.
- Marine & Subsea Navigation: Crucial for underwater Remotely Operated Vehicles (ROVs) and Autonomous Underwater Vehicles (AUVs) to navigate accurately.
- Industrial & Industrial Robotics: Used for platform stabilization, antenna stabilization, drilling applications, and industrial automation.
