Safran Electronics and Defense has successfully carried out integration tests of its Sigma 40 ship navigation system with the alignment system of the AGM-84 Harpoon anti-missile system.

The test was carried out within the scope of a contract signed with Korean naval shipyard DSME, Safran said in a statement.

The company also worked with Harpoon manufacturer Boeing on the tests.

The systems are intended for Krabi corvettes and KDX-class frigates deployed by the Royal Thai Navy.

After the successful tests, Safran's inertial navigation systems can now be used in all of Thailand's warships.

The Sigma 40 system is also used for conventional navigation and stabilization functions on ship sensors and weapons.

Sigma 40 navigation systems are built around a ring laser gyro inertial core, offering sustained precision and a high degree of operational flexibility.

Sigma inertial navigation systems are now fitted to combat systems on more than 500 warships, including the latest front-line ships such as the Charles-de-Gaulle aircraft carrier, Europe's Freem and Horizon frigates and helicopter carriers.
