Seafloor HyDrone — AutoNav Plus Configuration with Trimble Access GNSS Software

Achieve fully automated, survey-grade hydrographic data collection with the Seafloor HyDrone — AutoNav Plus Configuration, engineered for autonomous USV operations in rivers, lakes, reservoirs, ponds, and protected near-shore environments. Built on the HyDrone’s ultra-stable catamaran hull platform, the AutoNav Plus package adds advanced autonomous mission planning, GNSS-guided navigation, intelligent path following, and enhanced onboard processing—ideal for high-accuracy bathymetry and repeatable survey workflows.

With AutoNav Plus, operators can predefine missions, upload waypoints, enable adaptive track-keeping, and execute autonomous lines with superior precision. Real-time telemetry and mission monitoring enhance confidence, efficiency, and repeatability, even in dynamic survey conditions. This bundle also includes Trimble Access GNSS software (data collector not included), enabling seamless integration with professional GNSS workflows for hydrographic applications.

Designed for professional hydrographers and technical users, this configuration supports high-capacity sensor payloads, remote diagnostics, data redundancy, and long-duration autonomous operation—maximizing productivity while reducing operator workload.
