Sagem modernizes submarine navigation systems

  • 04-Dec-2009 03:12 EST

Sagem, part of the Safran Group, will be supplying its Sigma 40XP inertial navigation system to the French navy as part of an effort to modernize France’s SNA-class nuclear attack submarines. The Saphir was already fitted with one of the systems and its effectiveness was demonstrated during operational trials at sea. Two inertial navigation units, which include high-performance laser gyros and advanced digital filtering techniques, will be integrated in each submarine’s combat system. Sagem also supplies the optronic, electronic warfare, and radar mast system on the French navy’s nuclear attack submarines, intended for use in surface actions. Sagem’s navigation systems are used on more than 300 ships deployed by 31 navies worldwide, including surface vessels and submarines with nuclear, air-independent, and conventional propulsion.
