SIGMA 40, an attitude/heading and inertial navigation system, optimizes sensor, weapons and self-defense equipment on warships. All SIGMA solutions are based on high-grade Ring Laser Gyros technology, making navigation systems highly reliable with excellent long-term measuring accuracy. Sigma 40 is complete and upgradeable, easy to install, maintain and use on all surface vessels. In order to cover your various operational needs, it is available in several versions or solutions like SIGMA 20M, a gyrocompass designed for demanding naval applications. SIGMA 40 is used by 40 navies and is the world's top-selling naval inertial navigation system.
Onyx™ is an innovative navigation grade inertial module based on Safran Electronics & Defense's latest resonator gyros, the HRG Crystal™. Onyx™ delivers medium to high navigation grade performance and is perfectly suitable for civil and military oriented INS. It can be used in all applications: air, sea, space and, in the land sector.
This inertial module integrates unmatched characteristics in terms of compactness, reliability and precision. Thanks to the HRG Crystal™, Onyx™ can now achieve: 1 liter, 1 kilogram and 1 mils.
Capitalizing on Safran Electronics & Defense's 70-year experience in inertial technologies, Sigma 20M is a compact strap down and cost-effective full MIL-Spec gyro compass & AHRS. Based on advanced Hemispherical Resonator Gyros (HRG), Sigma 20M expands the well-known Sigma 40 Ring Laser Gyro INS family, the world's high performance best-selling naval INS.
Thanks to its solid state technology, Sigma 20M is maintenance free and provides unrivalled reliability and operational availability. Sigma 20M does not require GPS aiding to deliver full accuracy. It makes it the perfect solution in GPS denied situations.
The Sigma 40 inertial navigation system is making use on laser gyro technology. An advanced system designed by Safran Electronics & Defense for maritime applications, the Sigma 40 meets the most demanding navigation and weapon system stabilization requirements.
Both an inertial attitude and heading reference system, the Sigma 40 offers high performance and precision for all sizes of surface vessels. Both compact and robust, the Sigma 40 delivers all data needed for navigation: heading, roll and pitch, angular velocity, position and heave, vertical/horizontal speed and acceleration.
The Sigma 40 is suited to all types of platforms, including fast patrol boats, mine-hunters, corvettes, frigates, aircraft carriers, etc. It comprises an inertial navigation unit (INU), control and display unit (CDU) and an installation bracket, for fast removal and reassembly without recalibration. Both innovative and scalable, the Sigma 40 is easy to install, maintain and operate.
