Inertial navigation
for surface operations
Quadrans, Octans, Hydrins, Phins
Exail offers a complete range of Fiber-Optic Gyroscope (FOG)-based Attitude and Heading Reference Systems (AHRS) and Inertial Navigation Systems (INS) dedicated to maritime surface applications. Highly reliable and performant, Exail systems provide extremely robust navigation information in environments that experience long-term GNSS outages. For many years now, they’ve been the preferred surface navigation systems for major operations in the challenging offshore and hydrographic industries.
Unmatched performance for challenging long-term GNSS denied environments
Scalable performance thanks to FOG technology
Exail leads in inertial navigation technology by controlling its entire value chain. We design and manufacture all components in-house, from FOG gyroscopes to accelerometers, electronics, software, and algorithms. This vertical integration allows us to optimize performance and tailor our navigation systems to meet diverse requirements by adjusting the coil dimensions of our fiber optic gyroscopes.

A robust inertial technology
Exail navigation systems, based on Fiber Optic Gyroscope technology using light spinning in a fiber coil, have no moving parts, ensuring high reliability. Trusted globally for 20 years, they operate in extreme conditions: subsea and space, proving their robustness and precision.
A robust inertial technology
Unmatched MTBF
Exail core technology powers all our inertial products, operating in various applications. With millions of working hours and a strong track record, our FOG technology thus reaches over 500,000 hours, whereas most of Exail products boast a proven MTBF over 150,000 hours.
Unmatched MTBF
Lowest cost of owner ship
Inertial sensors is usually expensive due to preventive and curative maintenance, FOG-based sensors such as Exail’s offer very low cost of ownership due to their high reliability. With a breakeven advantage of less than 5 years, Exail AHRS and INS, are highly cost-effective solutions.
Lowest cost of owner ship
Powering easy operations
Easy to integrate
Exail AHRS and INS feature multiple output ports and protocol management for easy interfacing via serial or Ethernet, with compatibility for third-party sensors like DVL, EM log, GNSS, and custom protocols.
All-in-one devices
All our AHRS/INS are all-in-one devices, which means that they can be used in the same time well as for the IMO navigation, but also as an Motion Reference Unit, or for dynamic platform positioning.
ITAR-free for worldwide operations
Exail AHRS and INS do not include any component subjected to the ITAR regulation. They are ITAR-free solutions that can be shipped and used on any of your global surface applications.
A user-friendly interface
All Exail inertial devices are based on a web interface to be easy to operate and makes it user friendly. This web MMI has the same look and feel for all Exail products which simplifies the handling by the user.
Increased performance through aiding sensors
Exail AHRS and INS systems offer high autonomy with minimal drift, depending on specifications. Their performance is further enhanced by advanced embedded algorithms that leverage data from aiding sensors (DVL, EM log, GPS, USBL, LBL, and depth sensors) to boost accuracy and reject incoherent inputs, ensuring robust navigation.
