OCTANS NANO

4 000 m depth rating

0,5 deg heading accuracy

OCTANS NANO is the smallest and most adept state-of-the-art 4 000 m depth rated attitude and heading reference system (AHRS). It is built on iXBlue’s renowned fiber-optic gyroscope (FOG) technology and offshore instrumentation expertise. OCTANS NANO offers an outstanding price/performance solution, with rugged titanium housing, meeting the most challenging requirements of subsea applications.
