to modernize navigation system on South Korea's KSS-1 submarines
a hard-fought international competition, Sagem (Safran group) was chosen
by the South Korean Defense Ministry's Defense Acquisition Program Administration
(DAPA) to modernize the navigation system on the navy's KSS-1 class
Chang Bogo submarines. Each KSS-1 will be fitted with two Sigma 40XP
systems, integrated in the ship's combat system.

The technical qualities
of the Sigma navigation systems proved decisive in DAPA's decision, further
confirming the South Korean navy's confidence in Sagem, which already
provides navigation systems for its surface vessels.
Developed and produced by Sagem, the Sigma 40XP is a state-of-the-art
inertial navigation system, combining high-performance laser gyros and
advanced digital filtering techniques.
The core laser gyro technology has amply proven that it is the most appropriate
technology for the harshest operational environments, such as those experienced
by submarines during dives. By modernizing the KSS-1 class submarines'
navigation system, they will significantly enhance operational capabilities
to meet the evolving needs of the South Korean navy.

This latest business
win consolidates Sagem's leadership in the high-performance navigation
market for submarines. Sagem navigation systems now equip 11 different
classes of submarines, nuclear, air independent propulsion, and conventional,
totaling over 50 ships, along with some 300 surface vessels.
(1) The KSS-1 is a conventional type U-209 submarine displacing 1,200
metric tons. It is built by
Daewoo Shipbuilding & Marine Engineering.
