iXblue and ECA Group reportedly demonstrated successful subsea asset tracking in shallow waters using iXblue Gaps M7 USBL (Ultra Short BaseLine) positioning system and ECA Group new R7 ROV (Remotely Operated Vehicle).

Hosted by their local partner THESTA, a Polish company providing maritime navigation services and communication systems for the defense sector, the demonstration was organized for the Polish Naval Academy and NAVSUP 2022 attendees with the aim of showing that accurate positioning of underwater targets is possible in a potentially hostile and fast-approaching environment, in coastal regions characterized by shallow waters and often limited access.

As part of the mission scenario, ECA Group’s R7 ROV investigated objects and structures submerged in the shallow waters of the Baltic Sea in Gdynia harbor. iXblue Gaps M7 USBL acoustic positioning system was deployed to geolocate the R7 ROV and correct its trajectory in real time. A fixed transponder was also placed several hundreds of meters away from the vessel, at only 5 meters deep. The trials were carried out in water depths of 7 to 10 meters, surrounded by many docks and vessels causing significant acoustic echoes.

Despite challenging acoustic conditions, the positioning of the ROV and the transponder was stable and accurate. Extremely efficient in shallow waters, Gaps M7 ensured excellent horizontal tracking capabilities with omnidirectional coverage and 200° acoustic aperture.

“The R7 ROV along with the Gaps M7 USBL acoustic positioning system is able to transmit information accurately, even in noisy and difficult acoustic environments. They both enable fast operation as well as regular and quick position updates, even in very shallow waters, which is a definite asset for the navies, given their need for a fast, clear and concise picture of the battlespace to quickly maneuver naval forces in the field.” saidCezary Majchrowicz, Technical Director at THESTA.
