Sagem’s SIGMA 40 nav­i­ga­tion sys­tems sur­pass 8 mil­lion hours of op­er­a­tion in ser­vice


The SIGMA 40 ship­borne in­er­tial nav­i­ga­tion sys­tem built by Sagem (Safran group) has passed the mark of 8 mil­lion hours of op­er­a­tion in ser­vice, demon­strat­ing ex­cep­tional re­li­a­bil­ity as shown by feed­back from many of the world’s navies. Th­ese re­sults un­der­score the su­pe­ri­or­ity of laser gyro tech­nol­ogy for nav­i­ga­tion sys­tems be­ing op­er­ated in harsh en­vi­ron­ments.

Part of the ship’s com­bat sys­tem, the SIGMA 40 features high­pre­ci­sion mea­sure­ments, re­li­a­bil­ity and per­for­mance sta­bil­ity over time. It sig­nif­i­cantly en­hances the ef­fi­ciency of a war­ship’s sen­sors, weapons and self-de­fense sys­tems.

Sev­eral ver­sions of the Sigma 40 are avail­able to cover the dif­fer­ent op­er­a­tional re­quire­ments on all types of ships: sur­face ves­sels (from corvette to air­craft car­rier), and the SIGMA 40XP ver­sion for con­ven­tional, AIP or nu­clear sub­marines.

The SIGMA 40 has been cho­sen by 35 navies, and is now the best-sell­ing naval in­er­tial nav­i­ga­tion sys­tem in the world.

The French navy has cho­sen the Sigma 40 for all ma­jor ships: FREMM and Hori­zon mul­ti­mis­sion frigates, Mis­tral com­mand and force pro­jec­tion ships, Ru­bis-Améthyste class nu­clear at­tack sub­marines and the fu­ture Suf­fren class nu­clear sub­ma­rine (Bar­racuda pro­gram), and most re­cently the Adroit ocean-go­ing pa­trol boat from the DCNS. In in­ter­na­tional mar­kets, the SIGMA 40 has been cho­sen for Bay­nunah corvettes (United Arab Emi­rates), Skjold pa­trol boats (Nor­way), the new stealthy frigates and Scor­pène sub­marines (In­dia), and PKX pa­trol boats, FFX frigates and, most re­cently, mod­ern­iza­tion of U-209 sub­marines (South Korea).
