We were looking for a compact, precise and cost-effective inertial navigation system. The Ekinox-D was the perfect match

The Perfect INS for USV-based Bathymetry

Like most unmanned systems, USVs have space and power constraints. Ekinox-D is the best INS to be integrated into this type of vehicle. Weighing less than 600 grams and low power (<7W), the Ekinox-D INS integrates an RTK dual antenna GNSS receiver for a centimeter-level position.

It provides a 0.05° attitude while delivering a 5 cm real-time heave that automatically adjusts to the wave period.

USV with Swath Bathymetry Sonar

SPYBOAT® Swan is an Unmanned Surface Vessel (USV) fully equipped for hydrographic operations in shallow waters. It is remotely controlled by an operator staying on shore, up to one kilometer away from the USV.

Swan conducts bathymetric surveys in areas where vessels cannot navigate such as riverbed, lake, reservoir, dam or harbor.


Swan is equipped with a swath bathymetry sonar
Equipped with a Bathyswath 2, a swath bathymetry sonar, the USV provides bathymetric and navigation information in real-time to the operator’s tablet PC. Swan is compatible with all hydrographic software.

Ekinox-D perfect fit to Survey-based USV operating in shallow waters

USV with Multibeam Echosounder

The Oceanscience Z-Boat is designed with the surveyor in mind. The hull shape, propulsion, radio communication, and on demand sonar instrumentation combine to offer an easy to use and powerful option for the hydrographic surveyor or land surveyor wishing to complete inshore hydrographic work. The custom integration for the University of Washington Tacoma delivered in May, 2016 included the Rugged Z-Boat 1800RP, SBG Systems’ Ekinox-D Inertial Navigation System, Teledyne Odom Hydrographic MB2 Multibeam, Teledyne RD Instruments RiverPro ADCP, a camera and onboard computer.
