The Otter is the ultimate hydrographic survey tool for mapping of sheltered and enclosed waters. With tight integration between the on-board control system that enables autonomy and the multibeam echo-sounder, a bathymetric survey can be executed with a simple, streamlined workflow. The Otter comes with a laptop providing the Vehicle Control Station, which allows live monitoring of sensor data quality parameters and visualisation of data coverage in the same graphical user interface.

We focus on quality

We know the future is unmanned, and that effective and quality products improve our future


The custom Vehicle Control Station (VCS) allows the surveyor to plan the missions in a maritime chart based Graphical User Interface and also monitor the mission and the data acquisition quality while the USV is underway. Sensor and payload data can be monitored in the Vehicle Control Station. Multibeam data, swath width, coverage area, and quality parameters can be displayed in real-time on an intuitive user interface.

Custom Payloads

The Otter can carry a variety of customer defined sensors for seabed and environmental mapping. Quality control and monitoring of the sensor performance and coverage area are performed via the Vehicle Control Station (VCS). Sensors such as ADCP, CTD, fluorometers, hyperspectral imager and other environmental sensors is easily and cost-efficient integrated.


The autonomous future is electric, and the Otter is equipped with electric thrusters that are powered by up to 4 powerful and easily interchangeable battery packs. This gives the Otter a best-in-class endurance for its size.

Bathymetric Mapping System

Repetitive tasks like bathymetry are an ideal task for an automated robotic system. The Otter performs these tasks without the expense or extensive resources involved in traditional surveys. Ultra-compact singlebeam and multibeam sonar systems are available for integration for the Otter. This makes the Otter a turnkey bathymetric survey system for sheltered

We focus on performance.

The Otter is the newest member of our USV family. With a footprint of only 200 x 105 x 85cm and a weight of 95 kg, it is an easily deployable asset that can be transported in a van or even within normal airliners to the survey site. Electric propulsion and a tightly integrated bathymetric survey system makes this system a cost-efficient turn-key solution for bathymetric surveys in sheltered waters such as smaller lakes, canals, rivers, ponds and harbour areas.
