Sagem nav­i­ga­tion sys­tem for In­done­sian sub­marines


Sagem (Safran) beat out an in­ter­na­tional field to win the con­tract from Dae­woo Ship­build­ing & Ma­rine Engineering Co. Ltd (DSME) of South Korea as prime con­trac­tor for the nav­i­ga­tion sys­tem to be in­stalled on three 1,400-tonne ocean­go­ing sub­marines to be de­ployed by the In­done­sian Navy.

Or­dered by In­done­sia in 2012, this new class of ocean-go­ing sub­ma­rine is the first South Korean-de­signed sub­ma­rine to be sold in in­ter­na­tional mar­kets.

The Sagem nav­i­ga­tion sys­tem (NAVS) of­fers out­stand­ing re­li­a­bil­ity and pre­ci­sion, mak­ing it the best sys­tem for de­mand­ing sub­ma­rine mis­sions, whether at sea or for op­er­a­tions along coast­lines. NAVS com­prises two high-per­for­mance Sigma 40XP laser gyro in­er­tial ref­er­ence units, a com­puter and safety-crit­i­cal nav­i­ga­tion soft­ware, all con­tribut­ing to the sub­ma­rine’s stealth and safety dur­ing dives.

The de­ci­sive fac­tors in DSME’s choice were Sagem’s proven ca­pa­bil­i­ties as sys­tems in­te­gra­tor, plus its ex­per­tise in data fu­sion and trans­mis­sion to the ship’s com­bat sys­tem, along with ex­ten­sive ex­pe­ri­ence in man­ag­ing ma­jor de­fence pro­grammes.
