SBG Systems Unveils Ekinox Subsea Series

SBG Systems will unveil at SUBSEA EXPO (Aberdeen, U.K.) the Ekinox Subsea Series, a product family of survey-grade inertial systems designed for underwater applications – up to 6,000 m. Based on the robust and cost-effective MEMS technology, the series includes the Ekinox-M, a Motion Reference Unit (MRU), and the Ekinox-U, an underwater Inertial Navigation System (INS).

The Latest Technology for Cost-effective MRU & INS
The state-of-the-art Ekinox Subsea Series integrates the latest MEMS sensors to offer robust, small-sized, cost-effective, but exceptionally high performance MRU & INS. Ekinox outputs survey-grade roll, pitch, and heading (0.05°) at a high update rate, making it compliant with IHO standards. To obtain the most accurate and reliable navigation data, the internal Extended Kalman Filter fuses in real-time inertial and aiding information (DVL, RTK GPS, etc.). All collected data are recorded in the 8 GB data logger.

Advanced Real-Time and Delayed Heave
Ekinox offers highly accurate real-time heave which can be delivered on up to four different locations. The delayed heave feature allows surveying in every sea state. With this computation, heave accuracy is increased to 2.5 cm, while period swells can reach 50 seconds. To always get the best performance, the heave period is automatically computed and constantly adjusted.

Easy to Set Up, Reliable for Years
Without mounting orientation limitation, numerous serial and Ethernet ports, and an internal Web interface, Ekinox Subsea Series is easy to install, connect and configure. Available in long-life enclosure such as stainless steel or titanium, they are operational up to 6,000 m. Every product is calibrated from -20-60°C to ensure the highest data integrity in all conditions, and is shipped with its own calibration report.

Designed for Subsea and Surface applications
Ekinox-M makes hydrographic and offshore operations possible in all sea conditions by joining accurate motion measurement with delayed heave. Meanwhile, the Ekinox-U provides high accuracy navigation data in a compact and sealed package, making it the ideal solution for ROV orientation, AUV navigation, and data georeferencing.
