PARIS, Sept. 26 (UPI) -- South Korea has chosen Sagem of France to modernize the navigation system on its navy's KSS-1 class Chang Bogo submarines.
Each KSS-1 will be fitted with two Sigma 40XP inertial navigation systems, integrated in the ship's combat system.
The KSS-1 is a conventional type U-209 submarine displacing 1,200 metric tons and is built by Daewoo Shipbuilding and Marine Engineering.
Sagem's 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 systems, they will significantly enhance operational capabilities to meet the evolving needs of the South Korean navy, Sagem said.
It said the contract 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 more than 50 ships, as well as some 300 surface vessels.
