Sigma 95 Inertial Navigation Unit

Thanks to its versatile interfaces and open architecture, Sigma 95 family can integrate all available sensors such as GPS, Glonass, air data system, etc. It combines all the advantages of a SwaP optimized hybrid inertial navigation system in a single LRU.

With its optimal performance/mass trade-off, Sigma 95L inertial navigation system provides military helicopters, tactical aircraft and UAVs with navigation performance, accuracy and flexibility in a single LRU. Based on ring laser gyrometers as well as on its embedded GPS receiver combined with a powerful multimode Kalman filter, Sigma 95L optimizes its alignment capabilities.

Designed for the most advanced military aircraft, Sigma 95N provides high-grade navigation performance and accuracy, even in GNSS-denied environments. Based on highly accurate ring laser gyros, Sigma 95N also integrates an embedded GPS/GLONASS receiver combined with a powerful multimode Kalman filter.
