Cassidian has awarded a contract to SAGEM to supply its Sigma 30 Inertial Navigation System (INS) to upgrade the self-propelled M270 Mars Multiple Launch Rocket System (MLRS) artillery systems of the German, Italian and French armies.

Under the contract, five artillery regiments of the three armies will be upgraded to the Guided Multiple Launch Rocket System (GMLRS) configuration. Designed specifically for high-performance land navigation and artillery applications, the Sigma 30 system employs digital laser gyro technology for operation in demanding conditions. The system can either operate independently or coupled to a latest-generation selective availability anti-spoofing module (SAASM)-type GPS receiver and offers a pointing accuracy greater than one angular mil for azimuth and 0.5 mil for elevation.

The Sigma 30 enables high-precision firing of new unitary warhead rockets to a range of several dozen kilometres, including in an electronic warfare environment as a component of the European Fire Control System (EFCS) integrated into the rocket launcher system. The navigation system is also capable of the digitisation of 105mm light cannons and 120mm smoothbore or riffled mortars.

The system is used by NATO and more than 25 armies worldwide for towed and tracked howitzers, MLRS, and mortars including Caesar, Archer artillery systems, 2R2M mobile mortars, and the Pinaka multi-barrel rocket launcher in Europe and the Middle East.

The M270 MLRS is an armoured, self-propelled, multiple-rocket launcher designed to provide strike capability against air defence systems, enemy artillery, armoured formations and other high-value enemy targets. The launcher is capable of firing surface-to-surface rockets, the Army Tactical Missile System (ATACMS), and up to twelve MLRS rockets in less than 60 seconds.

The system is operational with the US, Bahrain, Denmark, Greece, Israel, Japan, South Korea, Norway, Turkey, the UK and the Netherlands.
