IMU 42, 42 cv & 42xp
Tactical inertial measurement unit
The IMU42 is a compact, lightweight, high performance Inertial Measurement Unit (IMU) featuring the best size/performance ratio available with extremely high bandwidth. The IMU 42 is ideally suited for applications requiring navigation, line-of-sight stabilization and flight control. It employs the latest closed-loop fiber-optic gyro (FOG) and linear rebalanced accelerometer technology. It is available in multiple configurations to meet different price and performance requirements.
Compatible for the following applications:
Guided Munitions
Anti aircraft and air defense missiles
Aerial pods
Advanced targeting pods
