A USV with echosounder carries an acoustic sensor to map biomass, plankton layers, and structure. A wind-propelled Sailbuoy runs planned transects for weeks to months, averages ~3 kn, and uses Iridium for control, telemetry, and alerts. The result is persistent fisheries acoustics with fewer crewed vessel-days.
The echosounder emits sound pulses and reads returns (echograms) to infer targets in the water column. Wind provides propulsion; solar powers electronics. With Iridium, operators adjust routes, check health, and receive summaries while the USV logs raw data for post-mission QA and analysis.
Continuous transects capture variability that short surveys miss. Endurance up to 12 months and geofenced routing enable long lines and repeat passes, improving trend detection while cutting mobilizations, CO₂, and HSE exposure.
Yes. Plan overlapping transects and maintain calibration/QA to compare time-aligned datasets.
Key parameters can be previewed over Iridium; full raw files are retrieved after recovery or via scheduled transfer paths where practical.
