Teledyne Marine SeaBat T50-ASV

Ultra-High Resolution Multibeam Optimized for Autonomous Platforms

Product Overview 

The SeaBat T50-ASV is a specialized evolution of the world-renowned SeaBat T50, specifically re-engineered for Autonomous Surface Vehicles (ASVs) and Uncrewed Surface Vessels (USVs). It maintains the same elite data quality of the T50-P (Portable) and T50-R (Rack-mount) but in a more compact, power-efficient form factor designed to maximize mission endurance on battery-powered platforms.

The system is defined by its Tracker Autopilot technology, which allows the sonar to operate autonomously—automatically adjusting settings like gain, power, and range to ensure optimal data quality without a human operator in the loop.

Processor Form FactorCompact OEM-style (IP21 rated for internal dry-mounting)
Power Input24VDC (Standard for ASV power rails)
  • Tracker Autopilot: A truly "hands-off" feature that optimizes sonar parameters in real-time. This ensures that even without a dedicated sonar technician on board, the ASV collects clean, survey-grade data throughout the mission.
  • Optimized Power Efficiency: Draws significantly less power (typical 90W) than standard ship-based systems, which is critical for extending the battery life and range of small ASVs.
  • Internal Data Storage: Includes a high-speed internal SSD within the sonar processor. Data is logged directly at the source, reducing the bandwidth requirements for the vehicle's telemetry link.
  • Fully Integrated INS: Can be supplied with an integrated Inertial Navigation System (INS) for precise time-tagging, motion stabilization, and georeferencing, all handled within a single interface.
  • Parallel Data Recording: Capable of recording bathymetry, snippets backscatter, sidescan, and water column data simultaneously without compromising ping rates.
