Polish Navy Upgrades gavia AUVs with Advanced T20-S Module

The Polish Ministry of Defense (MoD) is enhancing its underwater exploration capabilities through the acquisition of the RESON SeaBat T20-S Module from Teledyne Marine, specifically designed for the Gavia Autonomous Underwater Vehicles (AUVs).

strengthening Mine Countermeasure Operations

Since 2014, the Polish MoD has effectively utilized Gavia AUVs for mine countermeasures (MCM), currently operating a fleet of four advanced units, each boasting a range of complex features.

High-Resolution Bathymetric Data collection

The SeaBat T20-S Multibeam Echosounder (MBES), functioning at a frequency of 400kHz, provides exceptional bathymetric data with high positional accuracy, adhering to the International Hydrographic Organization (IHO) standards for hydrographic surveys.

Automated Pipeline Detection and Inspection

This innovative T20-S Module facilitates the automated identification of underwater pipelines, allowing for efficient tracking and inspection by the AUVs. This capability is vital for the Polish Navy’s inspections of critical underwater infrastructure,a key component in contemporary seabed warfare. Additionally,the T20-S Module generates essential backscatter data for effective mine classification. It is equipped with the latest Teledyne PDS Cube software, which enhances operational efficiency by enabling raw data visualization, post-processing, mosaicking, and direct export to the onboard Command-and-control system of the Kormoran Class Mine Countermeasure Vessels (MCMVs).

User-Friendly Modular Design

Thanks to the modular architecture of the Gavia AUVs, the Polish MoD can install the new T20 modules locally, eliminating the need for the vehicles to return to Teledyne Gavia for upgrades. This flexibility has solidified the Gavia AUVs as a reliable option for Explosive ordnance Disposal (EOD) and MCM operations.

Enhanced Performance in Diverse Operations

With the integration of the Teledyne RESON SeaBat T20-S MBES Module, Gavia AUVs are set to excel in collecting ultra-high-resolution bathymetric data, even during prolonged submerged missions at survey speeds between two to five knots.Their comprehensive sensor suite, which includes imaging technologies like the EdgeTech 2205 side scan sonars and teledyne BlueView MB2250 Micro Bathymetry Gap Filling Modules, positions these AUVs as ideal candidates for MCM, bathymetric surveys, and search and rescue (SAR) missions in continental-shelf waters and beyond.

Confidence in Advanced Underwater Operations

Teledyne highlights that the enhancement of Gavia AUV capabilities in Poland reflects the Polish MoD’s trust in their effectiveness for MCM and othre applications. These AUVs have proven their worth in EOD/MCM, SAR, critical underwater infrastructure inspections, and hydrographic survey missions.
