Sagem (Safran) to modernize the navigation and alignment system on Charles-de-Gaulle aircraft carrier

Sagem (Safran) has won a contract from French defence procurement agency DGA as prime contractor for the modernization of the inertial navigation and alignment system (SINA) on the Charles-de-Gaulle aircraft carrier.

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.
