Navigation systems for armored vehicles

Battlefield digitization requires better orientation and positioning capacities on armored vehicles. Safran Electronics & Defense offers solutions dedicated to observation and engagement on tanks and operational vehicles. Highly versatile, Sigma products are very easy to use and maintain. Epsilon10, the latest-generation terrestrial navigator based on Safran's patented vibrating gyro technology, allows armored vehicles in digitized environments to inform command/control systems, geolocalizing targets and friend positions. With no moving parts, its inertial sensor is highly robust and reliable.

GEONYX™: High precision and reliability under any conditions

Geonyx™ is the most compact, robust and reliable land inertial navigation and pointing system of the market. Geonyx™ combines high-grade autonomous or hybrid navigation, target geolocation, positioning and pointing accuracy in a SWaP system. Based on the HRG Crystal™, the proven pioneering hemispherical resonator gyro, Geonyx™ offers a real breakthrough in terms of operational efficiency, integration and costs of ownership.

Epsilon™: Trustful Coordinates Under Any Conditions

With the Epsilon family, Safran offers long lasting navigation performance INS*/GNSS* hybrid land navigation systems. Even in GNSS denied environment, Epsilon™ provides accurate position and heading for hours. Highly reliable and fully interchangeable, EpsilonOne and Epsilon10 offer the most cost-effective and ultra-compact navigation solutions for any generic vehicle platforms.
Epsilon™ family can also be integrated with small caliber guns like RCWS (Remote controlled Weapon Stations) to provide precision pointing for tactical missions.


Onyx™ is an innovative navigation grade inertial module based on Safran Electronics & Defense's latest resonator gyros, the HRG Crystal™. Onyx™ delivers medium to high navigation grade performance and is perfectly suitable for civil and military oriented INS. It can be used in all applications: air, sea, space and, in the land sector.
This inertial module integrates unmatched characteristics in terms of compactness, reliability and precision. Thanks to the HRG Crystal™, Onyx™ can now achieve: 1 liter, 1 kilogram and 1 mils.

Rate Gyro Unit 10 20 & 30MS56 series

Safran Electronics & Defense, due to its expertise covering all gyro's technologies (vibrating gyros, wheeled mechanical gyros, optical fibre and laser gyros) is able to propose the right technology for the best compromise between cost and accuracy required for each stabilisation requirement.
These units are equipped with a rugged single axis solid state vibrating rate gyro, which takes benefits of the 60 years of Safran Electronics & Defense experience in inertial systems.
The MS56 series is particularly designed for applications which need to combine very low signal noise and low cost, such as RCWS (Remote controlled weapon station), feed forward gyro for turret stabilization as well as commander sights. 

10, 20 & 30MS56 SERIES
Rate Gyro Unit 20BM60 & 20BM0060 series

Among the wide pannel of inertial sensors designed and manufactured by Safran Electronics & Defense, a dynamically tuned gyroscope has been selected in order to offer to the user the best compromise between accuracy required for stabilization purposes, robustness, reliability, and price. The 20BM60 unit box also includes a DC/DC converter and filters fully compliant with Mil Std 461 and Mil Std 1275.
20BM0060 is composed of the gyro and its associated servo-loop board, to be directly integrated into the customer system (sights, RCWS, etc.).
