SBG Systems has been designing solutions for marine applications dedicated to surveyors for the motion of their echosounders and for georeferencing for years. For even more performance, the company also completes its offer to surveyors with its in-house post-processing software, Qinertia.

This year, SBG Systems renewed its line of miniature inertial sensors with high-end functionalities and RTK called the Ellipse Series. The third generation of this product line bene? ts from a 64-bit architecture allowing high precision signal processing. All the INS/GNSS now embed a dual-frequency, quad constellations GNSS re- ceiver for centimetric position, and higher orientation ac- curacy. The Ellipse Series ? ts all kinds of marine applica- tions from enhanced subsea applications to hydrography with single beam or side-scan echo sounder. It is also a solution for ship motion and autopilots.

Ellipse is the smallest heave sensor at this level of perfor- mance, and the OEM version allows the tightest or deep- est integrations. All these features are made possible ei- ther in the 17-gram OEM version or the IP68 box version.

The Ellipse-D embeds a dual-antenna RTK GNSS, al- lowing heading in a few seconds, in all dynamic condi- tions, and even in challenging GNSS conditions. This in- ertial sensor provides unmatched precise performance in

Every RTSYS product relies on SDA (Synchronous

Data Acquisition) technology allowing high-comput- ing capacities and low-energy consumption. Twenty high-level engineers gather their skills in the company following four areas of expertise: acoustic signal pro- cessing, embedded electronics, softwares and under- water robotics and mechanics.
