TriDrone Unmanned Surface Vessel

Remote-control USV for hydrographic surveys

The TriDrone is a highly compact and portable trimaran USV that is specially designed to conduct hydrographic surveys in confined and remote bodies of water. Featuring a high-stability triple pontoon design, it folds into thirds, allowing it to be easily transported by a single operator.

The remote-controlled USV includes a hull-integrated single beam echosounder that can be customized to specific user requirements. The vessel’s maneuverable servo thruster allows it to conduct surveys in previously unreachable waters with superior precision and repeatability.

HyDrone Remote Control & Autonomous USV

Portable catamaran autonomous survey boat

The HyDrone is a one-person portable catamaran survey vessel that can be remotely controlled or powered by our AutoNav USV autopilot for autonomous operation. The lightweight, rugged vessel provides easy access to remote or hazardous areas, and is easily disassembled for transport and shipping.

The vessel can be monitored and controlled at long range in both manual and autonomous modes, and can carry out missions of over eight hours at 3 knots on a single battery bank.

The HyDrone is controlled via intuitive Mission Planner software that runs on a laptop and communicates via a radio telemetry link.

The HyDrone can be equipped with a variety of payloads, including ADCPs and single beam, multibeam and side scan sonar systems. It is particularly suited to our HydroLite Portable Echosounder kits, which provide high-accuracy depth measuring and logging for professional hydrographic survey applications.

EchoBoat-240 Unmanned Surface Vessel

USV for remotely-controlled or autonomous marine surveys

The EchoBoat-240 is an advanced remote-controlled and autonomously operating USV designed for the highest-resolution marine survey applications requiring high stability even under rough conditions. With powerful twin brushless DC outdrive motors and a payload capacity of 90 kg/200 lbs, the EchoBoat-240 can field state-of-the-art sensor suites for any requirements imaginable without sacrificing performance.

The highly versatile USV features multi-payload capacity and easily interchangeable sensor suites, and can be equipped with survey-grade single beam, multibeam, and side scan sonar systems. The vessel’s mounting well is designed around leading models including the Teledyne SeaBat T50/T20, the R2Sonic 2024, or the Norbit iWBMS-STX.

The EchoBoat-240 features our innovative AutoNav USV autopilot module, which allows you to easily pre-plan a mission, upload the mission to the vessel, and launch for fully autonomous operation. Upon completion, the vessel will loiter in place.

The USV can be monitored within line-of-sight range, and can be upgraded with additional hardware to enable over-the-horizon monitoring. All data is stored via an onboard PC with a direct cable connection, and a remote data link provides full equipment control and data acquisition. The USV can be easily switched from autonomous to remote control via a long-range remote control unit (RCU) that can operates at distances of up to 2km.

The two-person transportable vessel can be launched from a trailer or cart, or from a manned survey boat via a davit. It is ideal for standalone operations or as a force multiplier for a crewed vessel, operating either in the shallows or alongside the main boat.

We can tailor the EchoBoat-240 to your individual requirements, providing the vessel with a desired sensor payload pre-installed, or set up ready to accept existing systems from your survey equipment pool. We can also develop customized cabling that allows the vessel to interface with a variety of GPS, GNSS and RTK positioning systems.
