Nexter Systems has awarded a contract to SAGEM to supply SIGMA 30 navigation and pointing systems for integration into CAmion Equipé d’un Système d’ARtillerie (CAESAR) gun-howitzer systems.

Around 37 systems will be supplied by Sagem for use in CAESAR guns, which are scheduled to be delivered to an undisclosed Asian customer.

Based on Sagem’s advanced digital ring laser gyro technology, the SIGMA 30 is the reference inertial navigation system (INS) for use with a range of artillery applications, including howitzers, multiple rocket launchers, mortars and light guns, in jammed, spoofed or GPS denied environments.

Mounted on the cannon, the system, which is manufactured at Sagem’s Montluçon plant in France, offers totally independent operation, and can also be integrated in more complex systems, such as positioning and azimuth determination system.

The system is installed in all CAESAR artillery systems in service with militaries worldwide, including those deployed by the French Army in demanding theatres, including Afghanistan and, most recently, Mali, for Operation Serval.

"The system offers totally independent operation, and can also be integrated in more complex systems."

In addition to the CAESAR guns, the system also features in 40 other artillery systems, including PzH2000 howitzer, M270 multiple launch rocket system (MLRS), Nora self-propelled howitzer, BAE Systems Archer and the 2R2M mobile mortar.

Built by Nexter Systems, the CAESAR is a wheeled, 155mm 52-calibre self-propelled howitzer, and is designed to meet the fire support requirements of rapid deployment forces during combat operations.

The gun is currently operated by the French, Indonesian, Saudi Arabian and Thai militaries.

The contract’s value and delivery schedule remain undisclosed.
