Navigation systems for defense

Le Gyroscope résonnant hémisphérique – GRH – cœur de la nouvelle centrale de cap et d’attitude BlueNaute.

Setting the global standard in inertial navigation systems, Safran provides powerful positioning solutions that meet the full range of defense requirements: aircraft, ships and land vehicles.

The inertial reference units developed by Safran are at the heart of weapon systems. They provide precise navigation and positioning information to combat platforms, whether for firing or munitions release. 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. These high-tech systems are fitted on over 350 ships, especially Europe's new FREMM multi-mission frigates.

High-performance solutions

Sigma 95N est un système de navigation haute performance conçu pour des applications aéronautiques exigeantes, nécessitant une grande précision de navigation et de guidage : avions ou hélicoptères de combat, avions de surveillance maritime (Patmar), d’alerte avancée (Airborne Early Warning), etc.

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. Offering outstanding performance, it is already in service with some 20 navies worldwide. Safran's navigation systems have been chosen by about 30 navies, including those of Australia, South Korea, Norway and France.

Out on the battlefield, artillery systems have to offer high precision. Safran's Sigma 30 is the ideal solution in response to the growing need for precision navigation and positioning, due to the increasingly digital battlefield. Drawing on our innovative laser gyro technologies, Safran provides artillery solutions for about 20 countries. The Sigma 30 family combines versatility and outstanding performance, even under the most difficult conditions (heat, cold, rough terrain, etc.).
