Fiber optic gyroscopes (FOGs) are classified into three levels: Tactical-grade ($3,000–$8,000): Used in UAVs, ground vehicles, and basic stabilization systems; Navigation-grade ($8,000–$20,000): Common in maritime navigation, survey equipment, and autonomous systems; Strategic-grade ($20,000–$100,000+): Deployed in missiles, submarines, and high-end aerospace platforms.

Gun-hard MEMS IMU is engineered to survive more than 10,000g shocks while maintaining high bias stability, making them ideal for precision guidance in rockets, glide bombs, and artillery shells. These sensors combine advanced shock-dampening materials, AI-driven thermal compensation, and triple-redundant accelerometer arrays to outperform traditional MEMS IMUS.

A MEMS IMU is a sensor that measures a drone’s acceleration, angular velocity, and sometimes even its magnetic field. It’s made up of accelerometers, gyroscopes, and magnetometers. These components give us the data to track the drone’s orientation, position, and motion.

An Inertial Measurement Unit (IMU) is a device that measures an object’s acceleration, velocity, and orientation. The IMU’s role for loitering missile is essential for ensuring that the missile reaches its target with accuracy.
