Petra 3000

FOG Land Navigation Family

The PETRA 3000 FAMILY

The PETRA 3000 family of Land Inertial Navigation Systems (INS) with embedded GNSS best exploits the strapdown Fiber Optic Gyro (FOG) technology for high-precision pointing, localization and navigation achieving optimal performance.

Thanks to innovative integration of ITAR-free inertial sensors, designed and manufactured in Italy, with andvanced state estimation techniques based on Kalman Filter algorithm, completely developed and tuned in-house, the PETRA 3000 family provides the end user with superior pointing accuracy in GNSS denied environment.

Aimed to withstrand harsh operational conditions, PETRA 3000 is ideally suited for new and retrofit land vehicles programmes.

The PETRA 3000 products family provides maintenance-free, robust, low weight, compact volume land inertial navigation and pointing solutions without compromising performance in all operational environments.
