Airborne Inertial Navigation Family

INS/GNSS Navigation and Stabilization System

The ARGO family of Airborne Inertial Navigation Systems (INS), based on proprietary strapdown Fiper-Optic (FOG) design, is engineered to deliver maximum accuracy and reliability at minimal total cost of ownership.

The state-of-the-art ING and AHRS (Attitude Heading Reference Systems) solutions offer outstanding navigation and stabilization capabilities, thanks to the advanced state estimation techniques based on Kalman Filter algorithm and the innovative integration of in-house designed and manufactured ITAR-free inertial sensors, which can be coupled to GNSS for automatic initialization and highly calibrated hybrid data output.

The ARGO products family provides maintenance-free, robust, low weight, compact volume airborne inertial navigation solutions without compromising performance in all operational environments, including helicopters and fighters.

All navigation products are designed with maximum flexibility to enable smooth adaptation in both retrofit and new aircraft installations.
