Sagem to Modernise Navigation System of ROK Navy Submarines

摘要

After a hard-fought international competition, Sagem (Safran group) was chosen by the South Korean Defence Ministry's Defense Acquisition Programme Administration (DAPA)to modernise the navigation system on the 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 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.
