IMU 42 & 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:
IMU 42/42xp Benefits
The IMU42 is offered in two performance grades, a variety of configurations, all in the same compact form.
Form, fit and function performance replacement for other known IMUs.
Suitable for LOS stabilization, missiles, and demanding environments
Our products are ITAR-free and are entirely designed and developed in-house
The IMU 42 is a tactical grade IMU containing closed-loop fiber optic gyros and linear rebalanced accelerometer technology. The IMU 42 is a versatile inertial measurement system and comes in a variety of configurations supporting both navigation and control messages, several communication regimes tailored for different applications, with interfaces matching a legacy FOG unit. The IMU42 and the IMU42XP offer unmatched SWaP to performance ratio. Similarly to other Cielo products – the unit supports an advanced BIT with detailed fault isolation.

Cielo Inertial Space Solutions
Space applications require accurate, high bandwidth systems.
Additional unique requirements include the absolute need for observation systems to provide
line-of-sight stabilization pointing and to overcome the behavioral problems often caused by radiation in space.
Cielo has developed an advanced new generation IMU system
based on the closed loop Fiber Optical Gyroscopes (FOG) and linear rebalanced accelerometer technology.
