Inertial Measurement Unit Pack Octans Nano OEM (AHRS)

The Octans Nano OEM is an inertial measurement unit (IMU) of the AHRS (Attitude Heading Reference System) type designed by Exail (formerly iXBlue). It provides accurate data on a platform's attitude (roll and pitch) and heading. It is optimized for integration into professional marine systems.

An AHRS (Attitude Heading Reference System) like the Octans Nano OEM focuses on providing orientation data (roll, pitch, heading). An IMU (Inertial Measurement Unit), on the other hand, is a sensor that measures specific forces (accelerations) and angular rates. A full inertial navigation system (INS) often uses an IMU and also integrates positioning capabilities, typically in combination with an external GNSS system, which an AHRS does not inherently do.

This pack is specifically designed for marine system integrators and boatbuilders. It is not a "plug-and-play" solution for end users, but a component optimized for integration into larger, more sophisticated system architectures.

The Octans Nano OEM primarily provides orientation data, including:

Roll (side-to-side tilt)Pitch (fore-and-aft tilt)Heading (horizontal orientation)These data are essential for stabilization and motion compensation.

Exail (formerly iXBlue) is recognized for its expertise in inertial technologies and high-precision navigation and positioning systems for marine and underwater environments. The Octans Nano OEM benefits from this expertise, providing a reliable and accurate solution for critical applications.

"OEM" stands for Original Equipment Manufacturer. This indicates that the product is designed to be a component integrated into a larger final product manufactured by another company. The Octans Nano OEM Pack is therefore intended to be incorporated into complex systems rather than being used as a standalone device by the end user.

Thanks to its precision in attitude and heading, the Octans Nano OEM is used in various professional applications, including:

Dynamic positioning systems (DP)
Multibeam sonars
Antenna stabilization systems
Underwater inspection platforms
Marine navigation and charting systems

Yes, the Octans Nano OEM is designed by Exail, a company specializing in solutions for marine and underwater environments. While the exact robustness specifications are not detailed here, the brand is known for the reliability of its equipment in harsh conditions.

The Octans Nano OEM is designed to provide high-fidelity attitude and heading data. Its advantages include minimal drift and high responsiveness, essential characteristics for critical applications requiring a stable motion data base.

No, the Octans Nano OEM is an AHRS, meaning it provides attitude and heading. It is not a complete navigation system that would also include absolute positioning capabilities. It is typically used as a complement to an external GNSS system for navigation applications requiring position data.

The Octans Nano OEM inertial measurement unit is manufactured in France.

Integrating the Octans Nano OEM requires technical skills in systems engineering. Prerequisites typically include a stable power supply, an appropriate mechanical mounting platform, and the ability to develop or integrate software interfaces to communicate with the central unit and process its data.

As with most high-precision inertial measurement units, alignment and potentially calibration or performance verification may be required after mechanical installation to ensure optimal heading and attitude data accuracy relative to the host platform. Specific details depend on the integration manual provided by the manufacturer.

Inertial measurement units (IMUs) like the Octans Nano typically provide standard industry communication interfaces to simplify integration. These may include serial ports (RS-232, RS-422) or Ethernet interfaces, enabling the transmission of attitude and heading data to the host system.

To ensure optimal performance, the Octans Nano OEM must be mounted on a stable and rigid platform, minimizing vibrations and deformations. Precise alignment of the IMU relative to the host system's reference axes is critical for accurate attitude and heading data. Detailed mounting instructions are provided in the product's technical documentation.

Yes, the Octans Nano OEM is designed to be used in conjunction with an external GNSS (Global Navigation Satellite System). The AHRS provides attitude and heading data, while the GNSS supplies position information, enabling a more complete and robust navigation solution when these two systems are integrated.

Yes, the Octans Nano OEM is perfectly suited for integration with multibeam sonar systems. The precise roll, pitch, and heading data it provides are essential for compensating vessel movements and ensuring the accuracy of bathymetric measurements and underwater mapping.

Yes, the Octans Nano OEM is a key component for dynamic positioning (DP) systems. High-precision attitude and heading data are vital for fine control of thrusters and rudders, enabling a vessel or platform to maintain a fixed position and orientation despite external forces such as wind and currents.

As an OEM product intended for integration, the Octans Nano OEM is designed to interact with a variety of third-party software via its standard communication interfaces. Integrators are responsible for developing the drivers or bridges required for their visualization, control, or data processing software to interpret and use the data provided by the IMU effectively.
