The ECHO Glider is an autonomous, buoyancy‑driven underwater vehicle designed for long‑endurance monitoring, inspection, and environmental data acquisition in offshore and coastal domains. Its architecture combines low‑power propulsion, adaptive buoyancy control, and streamlined hydrodynamics to deliver persistent operations with minimal energy consumption. The platform supports modular sensor payloads, enabling rapid configuration for applications such as subsea cable inspection, offshore renewable asset monitoring, water‑column profiling, and environmental assessment.

ECHO’s control system integrates real‑time navigation, mission planning, and communication protocols to ensure reliable performance across varying sea states and operational scenarios. The vehicle transitions smoothly between surface and submerged modes, maintaining stability and precise vertical motion through its ballast and trim systems. Designed for deployment from small vessels, the glider offers efficient launch and recovery workflows suited to research, commercial, and industrial operations.

With validated core functions demonstrated through recent sea trials, the ECHO Glider provides a scalable platform for next‑generation autonomous marine monitoring, supporting both scientific research and commercial exploitation pathways.
