Octans Nano is a compact subsea gyrocompass and Attitude and Heading Reference System (AHRS) from Exail designed for underwater navigation and attitude monitoring applications in demanding marine environments. Built on Exail’s proven Fiber-Optic Gyroscope (FOG) technology, the system delivers real-time heading, roll, pitch, and rate-of-turn data within a compact six-liter housing optimized for subsea deployment. With a rugged titanium enclosure and 6,000-meter depth rating, Octans Nano is engineered to support reliable performance in harsh underwater operating conditions.
Designed for ROV navigation, subsea vehicle guidance, and monitoring of underwater structures, Octans Nano combines high-performance sensing with streamlined integration capabilities. The navigation-grade AHRS features Ethernet and serial interfaces with sensor rebroadcast functionality, helping reduce cabling requirements while supporting both modern and legacy subsea architectures. Its solid-state FOG strap-down design provides dependable operation with low maintenance requirements and supports long-term deployment in offshore and underwater missions.
