Setting the global standard in inertial navigation systems, Safran provides powerful navigation and positioning solutions that meet the full range of defense requirements: aircraft, ships and land vehicles.
Thanks to its mastery of the full range of inertial technologies (mechanics, thermics, laser, optical fiber, resonant structure), Safran has consolidated more than 70 years of know-how in civil and military navigation systems operating in all environments. Combining attitude and heading reference with inertial navigation, the solutions developed by Safran offer a high level of performance and accuracy.
The inertial reference units developed by Safran are at the heart of weapon systems. They provide precise navigation and positioning information to combat platforms when engaged in missions, whether for their location or the pointing of weapons systems (artillery, missile, etc.), sensors (radars, optronics, etc.) or weapons itselves.They deliver invaluable assistance to these systems, while ensuring maximum security. On advanced fighters like the Rafale, they provide fully autonomous operation and resistance to electronic warfare. The European helicopter NH90 has also installed this technology.
In addition, Safran develops high-performance inertial and hybrid navigation solutions for surface vessels. The Sigma 40 system offers high-precision navigation on many different ships, from patrol boats to aircraft carriers, and contributes to the performance of shipborne sensors and the efficiency of self-defense systems.
On aircraft carriers, it's absolutely vital to harmonize the ship's navigation system with those on its aircraft – and Safran offers top-tier at-sea alignment solutions.
Submarines expect outstanding performance from their navigation systems during dives. The Sigma 40 XP (eXtended Performance) laser gyro system, developed and produced by Safran, guarantees the ship's ability to operate in a severe magnetic environment, without penalizing performance. This is obviously an ideal solution for new-generation submarines, or to modernize current units. The Sigma 40 XP meets the most demanding naval requirements. They are operational in more than 15 submarine classes around the world. Safran's navigation solutions have been adopted by more than 600 navies around the world, including those of Australia, South Korea, Norway, France and the United States.
Out on the battlefield, artillery systems have to offer high precision. Safran offers a complete range of inertial navigations systems that equip over 50 types of land platforms throughout the world: the Sigma 30 high-precision inertial unit, the Epsilon GNSS back up system and the latest product, Geonyx™, an inertial navigation and pointing system offering extreme shock resistance. Geonyx™ builds on the best characteristics of the Sigma 30 with regard to performance and robustness in the most extreme conditions. Thanks to its hemispherical resonator gyro called HRG Crystal™ which features innovative and proven technology, the Geonyx™ is the most compact, robust and reliable land inertial navigation and pointing system on the market.
