Cielo Inertial Solutions is a leading manufacturer of closed loop FOG based inertial systems.
For more than a decade, Cielo has supplied Israeli and international customers with high-performance, reliable, and ITAR-free inertial solutions at competitive prices.



Cielo is a global technology expert in inertial solutions, focusing on reference, control, stabilization, and navigation solutions for defense and commercial operations, with a full range of performance capabilities for applications on land, in the air, at sea, and in space. We are an innovative, agile company, with proven field experience, backed by strong and reputable corporate owners.

Since January 2014, Cielo Inertial Solutions has been equally owned by Rafael Advanced Defense Systems Ltd. of Israel, and Kearfott Corporation of America, two world leaders in defense technologies.


Cielo is the sole Israeli manufacturer of Closed Loop FOGs, IMUs, GyroCompass, North Finding Systems, and INS –  off the shelf as well as custom-tailored solutions – and has delivered products to top-tier defense industries in Israel such as RAFAEL, ELBIT, Israel Airspace Industries (IAI), Israel Military Industries) (IMI), and to many other system manufacturers in Asia, Europe and the Americas.

Our field-proven inertial solutions are integrated into fully operational systems, such as missiles, payloads, UAVs, civilian aircraft protection systems and many others. Since 2005 Cielo has demonstrated its capability to align its commitments to challenging requirements and deadlines – from tight-scheduled flight tests to high volume deliveries of hundreds of IMU systems per year – and actively partner in the success of high-end systems incorporating our products.

Cielo is dedicated to continuing development of its innovative inertial solutions, while maintaining our customer responsiveness.
