Sigma 95N is a high-performance navigation system designed for most demanding aeronautic applications that require high navigation and guidance accuracy.
The Sigma 95N INS is based upon three highly accurate digital laser gyroscopes. It is equipped with a GPS or GPS/Glonass receiver and makes use of a powerful multimode Kalman filter to optimize performance by hybridizing inertial and satellite data. It can also integrate NATO's new Selective Availability/Anti-Spoofing Module (SAASM) and in the close future, the Europe's upcoming Gallileo system. Its open design and versatile interfaces (Mil-Std-1553B, Arinc, Gost, etc.) allow easy integration in all types of avionic configurations and platforms.
