Safran Electronics & Defense navigation systems


The computers providing flight control on aircraft have to count on autonomous, accurate and dependable navigation systems to ensure safe, comfortable flights. Safran Electronics & Defense offers a wide range of navigation systems based on proven sensors. These systems also ensure the lowest operating cost on the market because of their optimized design. Our new SkyNaute family covers requirements for all types of airborne platforms – long range, single aisle and regional airplanes, helicopters and drones. SkyNaute family proposes hybrid inertial/satnav systems like ADIRU (Air Data Inertial Reference Unit) or attitude and heading reference systems like APIRS (Aircraft Piloting Inertial Reference System). We offer innovative navigation suites that can be integrated in critical avionics architectures.


Safran Electronics & Defense offers a complete range of navigation systems that cover all requirements in civil aviation, building on our long experience in the development and certification of all inertial sensor technologies:

  • Hybrid navigation systems, combining inertial and satellite sensors, plus air data management:
    • ARINC 738 / D0 229C / ARINC 429 / ADIRU with optical (GLR) or vibrating (GRH) gyroscope.
  • AHRS: Attitude and Heading Reference System:
    • APIRS (Aircraft Piloting Inertial Reference System) with fiber optical gyroscope (FOG).


The hemispherical resonating gyro - HRG - the heart of the new center heading and attitude BlueNaute.
The specific know how of Safran Electronics & Defense Germany GmBH (Murr) is based on the Fiber-Optic Gyro (FOG) technology. The company has a long and in-depth experience in design and fabrication of fiber-optic components and optics subassemblies as building blocks of the FOG.
