The Swedish Defence Materiel Administration (FMV) has awarded a contract to maritime navigation company iXblue to deliver 172 Quadrans gyrocompasses.

Under the four-year contract, the company will equip the Swedish Navy’s fleet of CB90 combat boats with fibre-optic gyroscope (FOG)-based Quadrans navigation systems.

iXblue commercial director David Cunningham said: “The FMV was seeking new maintenance-free and high-performance gyrocompasses for the retrofit of their fleet of high-speed crafts.

“Our fibre-optic gyroscope (FOG) technology having no moving parts and offering exceptional reliability, was identified as an ideal solution to keep maintenance costs down. Another key aspect was the performance delivered by these gyros.

“The CB90 vessels are indeed very fast boats and need the most reliable and accurate heading and attitude data to navigate safely.”

Developed around the Fiber-Optic Gyroscope technology, the Quadrans gyrocompasses are solid-state and strap-down systems providing accurate heading and attitude data.

This allows high performance at high speeds in challenging environments, even in Global Navigation Satellite System (GNSS)-denied settings.

The compact, lightweight Quadrans Gyrocompasses are easy to install on small-sized crafts and consume less power.

The open architecture of the system permits seamless interfacing with all GNSS systems and other third-party navigation software.

Cunningham added: “Our Marines Series Inertial Navigation Systems being already in service on the Gotland-class submarines and Koster Class MCMV’s, and our Quadrans gyrocompasses equipping other surface boats in the Swedish Navy fleet, the FMV was familiar with the high-performance delivered by our systems and knew the Quadrans met the specific requirements needed for the CB90.”

In January 2018, Naval Group awarded a contract to iXblue to install navigation systems on five of the French Navy’s new 4,000t frigates.
