This naval drone is able to adapt its operating depth to environmental conditions and avoid blind zones which can be due to sound speed stratification. Thanks to internal synchronization features, all sensors are working together providing very precise localized and very high quality data, obtained, especially on shadows, allowing to quickly recognize objects. In order to navigate with the precision required for the SAS, the UMISAS sonars use a technique protected by an ECA Group patent. UMISAS directly uses the data from the A18-M or T18-M inertial unit to perform SAS processing, thus eliminating the use of navigation sensors dedicated to the SAS sonars on the market, which are less efficient and therefore do not allow geo-referencing of the images formed, and above all are much less reliable. Thanks to this impressive feature, it is for sure one of the easiest drones to manoeuvre. What makes the DTG2 such a great drone is that it boasts the Deep Trekker pitching system. The positioning of the support required to form the synthetic antennas is an integral part of the UMISAS process. The following are eight of the best underwater drones that are currently on the market. What you need to know: The PowerDolphin is an amazing drone if you want to capture. PowerVision PowerDolphin Water Surface Drone With 4K UHD Camera. The UMISAS sonars on board the A18-M AUV and T18-M towed sonars are interferometric synthetic aperture sonars (InSAS) that aim to obtain a spatial resolution in the order of 3cm x 3cm to best classify small and irregularly shaped objects (in the order of 50cm on the side perpendicular to the sonar's axis of view). Best underwater drone for cinematography.

The 18-M is equipped with a Synthetic Aperture Sonar (SAS) for high resolution imagery, Multibeam Echosounder (MBES) or Volume Search Sonar (VSS) can also be fitted. Thanks to its unique 3D navigation accuracy, outstanding data can be gathered from different sensors in a single survey.

High quality data for high precision cartography with a New Generation SASĪ18-M provides accurate seabed survey capabilities due to its high stability which makes this AUV much less affected by waves than a surface ship or a towed system.
