Project planning guide
Plan the USV, sounder and positioning workflow together
An unmanned surface vessel is most useful when its payload, positioning and route plan match the waterway and deliverable. Start with the survey area, launch and recovery conditions, expected depth range, current, obstacles and the data that must be delivered to the client.
For bathymetric work, the echo sounder, GNSS correction method and sound-speed or draft process should be planned as one workflow. A reliable field plan also includes line spacing, coverage checks, communication, safety procedures and data backup.
Before mobilization
Practical planning checks
Align the vessel, payload and survey workflow before the team reaches the water.
- 01Match USV size and payload to the launch site, water conditions and survey coverage.
- 02Define the echo-sounder and positioning workflow before mobilization.
- 03Plan routes, safety checks, coverage review and data handover.
Frequently asked questions
Answers to the planning questions technical buyers typically resolve before requesting a configuration.
What should a hydrographic USV configuration include?
Start with the vessel, payload, positioning, correction workflow, field conditions and the intended survey deliverable. The final configuration should fit the launch site and operating plan.
Why plan the echo sounder and GNSS workflow together?
Depth observations and position records are used together in hydrographic deliverables, so the sensor, positioning and project-control workflow should be agreed before field work.
What should be checked before a river survey?
Check water conditions, launch and recovery access, route safety, line plan, correction availability, communication and the required quality-control process.
A More Practical Way to Survey Difficult Waters
Start with the water environment and deliverables. Then select the platform, positioning method and survey payload around the project.
Ports and waterways
Combine remote operation, route planning and selected hydrographic sensors for the working area.
Dredging and construction surveys
Match the vessel configuration to the required survey route, sensor and project output.
Water-quality and inspection missions
Use a configuration discussion to assess water-quality, side-scan or inspection payload requirements.
