Autonomous Water Vehicles

Accelerate Your Water Monitoring Program

Imagine simultaneously collecting data for water quality, water velocity, water flow, bathymetry, and photogrammetry in a single day, with a single YSI technician! A contract with YSI can allow you to get all the benefits of the HYCAT Autonomous Surface Vehicle and the i3XO Autonomous Underwater Vehicle - without the equipment budget, maintenance, personnel, and training that owners take on. When you let YSI drive, you'll enjoy all the benefits listed below!

Water Quality Data Collection

BREAK YOUR DATA COLLECTION SPEED RECORD

Get more high-quality, spatial and temporal data in one mission than ever before possible. With the i3XO Ecomapper AUV or the HYCAT ASV, you can cover between 130-180 acres per day at a single depth, when operating at the optimal speed of 2-3 knots. Multiple depths ("layers") are possible with the i3XO Ecomapper AUV. YSI technicians can adapt speed to optimize resolution, based on your project objectives.


Remote Water Monitoring

TAKE THE LEAD WITH TOP TECH

The top Xylem sensor technologies all come together in a single vehicle platform, but the autonomous and remote control features take the tech to the next level. One can take control of the HYCAT remotely to modify a mission based on real-time visualization of data via HYPACK MAX software. The Inertial Navigation System (INS) on the i3XO Ecomapper AUV enables you to localize data points with 0.3% accuracy!

THE YSI CREW IS HERE TO SERVE YOU

Make your project a winner, by bringing our unsurpassed application expertise. From Korea to King County, FL, our team has run missions with autonomous vehicles in canals, lakes, reservoirs, estuaries, and other environments. Each scenario brings unique requirements and risks. Save your team the ramp-up time associated with training and mastery of this technology. Let YSI Drive!


Unmanned Water Vehicles

CROSS THE FINISH LINE SAFELY

Keep your people safely ashore, while getting countless man-hours' worth of data. Certain environments are particularly hazardous-acid mine drainage, reservoirs, wastewater lagoons, industrial waste holding ponds are examples of places where an unmanned vehicle is not just preferred, its necessary. Protect your personnel (and ours!) by letting the vehicle do the work.


Why Use the i3XO Ecomapper AUV?

A key reason to use the i3XO EcoMapper AUV is when undulating and below-surface water quality mapping is desired. By contrast the HYCAT is a surface-only vehicle. The i3XO brings together an unprecedented array of sensor technologies on an autonomous underwater vehicle (AUV) of its size:

  • A specially modified EXO1 water quality sonde, capable of holding any 4 EXO sensors
  • Multi-beam, side-scan sonar for high-resolution mapping of the seafloor and surfaces
  • Advanced Doppler Velocity Log for bathymetry and downward-looking current profiling
  • An optional towable magnetometer, as well as the option to use an expansion port for additional sensors
  • A unique internal navigation system that enables 0.3% accuracy of distance travelled and geo-referencing of data points

Examples of work the i3XO has been used for include monitoring cooling ponds at iron mines for environmental contamination and turbidity, to ensure compliance with local regulations. it has been used for identification of unexploded ordnances and search and rescue missions. Dredging contractors have used floor mapping for depth, obstructions, and other details needed prior to dredging, to minimize impacts and guard safety. All sensors have supported spatial water quality profiling in estuaries, lakes and rivers for teaching, research, and regulatory purposes.

Why Use the HYCAT ASV?

The HYCAT is a one-of-a-kind autonomous surface vehicle (ASV) that brings a different set of sensors and capabilities than the i3XO EcoMapper. Another distinction is that, since it is always on the surface, data can be visualized in real time and mission planning can be adapted on the spot using HYPACK MAX software with a module designed just for the HYCAT. Some of the hallmark technology on the HYCAT includes:

  • A specially modified EXO2 water quality sonde, capable of holding any 7 EXO sensors
  • A SonTek HydroSurveyor M9 for hydrographic surveys
  • Hull-mounted side scan sonar for bottom mapping
  • An RTK GNSS Receiver for positioning and geo-referencing data

The HYCAT is being used globally. It has been used for pipeline surveys in international waters with collection of bathymetry, side scan sonar, and water velocity data collected in a high-current environment. Harmful algal bloom mapping is a popular application with both i3XO and HYCAT, but the HYCAT can access shallow coves and shore areas where blooms often accumulate. Importantly, the onboard SonTek HydroSurveyor supports discharge measurements, one of the most popular applications and one that is not available with the i3XO. Other surveys utilized the side scan sonar for search and rescue and the EXO2 water quality sonde for sediment transport.
