The Next-Generation 800 kHz Autonomous Mapping Solution
Product Overview
The SeaBat T51-ASV is the latest ultra-high resolution multibeam echosounder (MBES) optimized specifically for Autonomous Surface Vehicles (ASVs) and Uncrewed Surface Vessels (USVs). Released in 2023, it is built on the revolutionary 800 kHz technology of the SeaBat T51-R, offering four times the resolution of the previous T50-ASV flagship while maintaining a compact, power-efficient form factor.
It is designed for high-end autonomous mapping where mission endurance and extreme data detail are both non-negotiable. With its 0.25° receiver beamwidth, it allows for the detection of incredibly small objects, such as cables or individual boulders, at full swath width.
