The SIGMA 20 is a high-precision navigation and pointing system, calling on a breakthrough inertial technology, the hemispherical resonator gyro (HRG). This patented Sagem technology underpins navigation solutions combining outstanding cost-competitiveness and reliability.
Easy to integrate in combat platforms, Sagem's Sigma navigation systems are unaffected by jamming, and enable a weapon system to be used in the absence of GPS signals, including in the harshest operating environments.
The new SIGMA 20 navigation system, under production at Sagem's Montluçon plant since 2013, rounds out the company's offering of navigation and pointing systems for surface-to-air artillery systems.
Based on laser gyro or HRG sensors, Sigma navigation systems are used in more than 40 different weapon systems deployed worldwide.
Sagem has developed proven expertise in all inertial technologies (mechanical, laser, fiber-optic, vibrating), covering the full spectrum of land applications. The only company in the world to offer a complete range of civil and military navigation systems, Sagem draws on more than 60 years of experience and expertise.
The MPCV, or Multipurpose Combat Vehicle, built by MBDA as prime contractor, is a combat system fitted with guns or missiles. The short-range surface-to-air version is fitted with Mistral missiles, while the land combat version will be equipped with MMP medium-range missiles.
