Norwegian Navy Chooses Sagem Navigation System

Norwegian Navy has chosen Sagem’s SIGMA 40 navigation system for its offshore patrol boats.

Sagem (Safran) has won a contract to modernize the Navy’s navigation system on three Nordkapp class offshore patrol vessels. These armed, helicopter-carrier patrol boats, displacing more than 3300 metric tons, will be fitted with SIGMA 40 laser gyro navigation systems.

SIGMA 40 system performed well under the country’s specific maritime conditions: fjords, inclement weather, ice, etc. The system, which has also demonstrated long-term res shocks, complies with shock resistance specifications in the military standard MIL-S 901 D.

SIGMA 40 is a laser-gyro inertial system designed to guarantee high-precision navigation even in the harshest environments. A completely standalone unit, the SIGMA 40 contributes to the effectiveness of shipborne systems and also to the success of even the most demanding missions assigned to warships.

The SIGMA 40 navigation system is now used on more than 500 surface naval vessels and 75 submarines, especially the latest and most innovative front-line ships, such as the European FREMM and Horizon frigates, the Mistral class amphibious assault ship and the Korean LPX Dokdo amphibious helicopter-carrier. The SIGMA 40XP version of the system was chosen for the conventional Scorpène class submarines built by French naval shipyard DCNS, the modernization of the navigation systems on the Amethyst class nuclear attack submarines, and the upcoming Barracuda class submarines.
