Exail header inertial navigation for civil engineering

Inertial
navigation
for civil
engineering

Exail's Attitude and Heading Reference Systems (AHRS) and Inertial Navigation Systems (INS), incorporate Fiber-Optic Gyroscopes for reliable performance in civil engineering. Suited for tunneling, mining, construction, railway, and mobile mapping, these systems excel in challenging environments like GNSS-denied areas, ensuring undisturbed navigation, accurate georeferencing, and precise pointing amid obstacles such as buildings, trees, tunnels, and mines.

Reduce the cost of your industrial engineering operations

Civil engineering operations

Choosing a premium FOG INS/AHRS/IMU induces cost savings in the long run. On top of the inherent qualities of FOG (no maintenance cost, very low failure rate…), our systems’ high performance and quick bootup time means your operations will benefit from consequently lower idling time.
