System modernization mainly involves the replacement of the original gimbal type inertial reference units by very-high-precision Sigma 40 laser gyro inertial navigation units.
Sagem will gradually upgrade the Charles-de-Gaulle aircraft carrier navigation system. The system will supply:
- Navigation, guidance and attitude data in real time to the many onboard systems involved.
- Data allowing Rafale fighters to align their own laser gyro navigation systems, also supplied by Sagem.
Sagem continues to work with French shipyard DCNS on the integration of high-performance navigation systems that enhance the capabilities of its shipborne weapon and combat systems. The company's expertise is reflected in new functions, tested for effectiveness, and guaranteed performance throughout the development and production cycle, all while meeting the tight deadlines imposed by the Charles-de-Gaulle's maintenance schedule.
After completion of this program, the Charles-de-Gaulle aircraft carrier will deploy a navigation system fully equivalent to new vessels already equipped with Sagem's Sigma 40 system, including Mistral class BPC amphibious assault ships, Horizon and Aquitaine frigates (FREMM program) and the upcoming Suffren class nuclear attack submarines in the Barracuda program.
Sagem, a high-tech company of Safran, holds world or European leadership positions in optronics, avionics, electronics and safety-critical software for both civil and military markets. Sagem is the No. 1 company in Europe and No. 3 worldwide for inertial navigation systems (INS) used in air, land and naval applications. It is also the world leader in helicopter flight controls and the European leader in optronics and tactical UAV systems.
