Unmanned Survey Platform (USP) Calypso


The Unmanned Survey Platform (USP) Calypso is an inflatable, full autonomous surface vehicle that can carry a wide range of sensors for hydrographic and environmental surveys.

Calypso is connected to the cloud platform Atlantis for addressing the auto navigation module. The auto navigation module allows the calypso to interrogate augmented maps and to avoid objects and plan survey paths or survey areas. The maps can be consulted via a tablet connected to the cloud. Calypso will be controlled automatically based a defined survey area. Other optional Atlantis modules are data storage and data processing modules.

Calypso provides standard a single beam echo sounder, but various other types of sensors can be mounted on the platform as well, like a multibeam echosounder, a camera, lights, gas sensors, temperature sensors, ADCP or water sampler.

Calypso is connected via the cellular network to the cloud platform Atlantis. In general 3G or 4G services are used. Data services are adapted to the link quality. In case of a stable data link, data is streamed real-time to Atlantis for data processing and visualization. At remote locations, where no internet connection is available, the data can be stored locally. When back in range of internet connection, the data can be pushed towards Atlantis.


All data is collected in dotOcean’s software platform, Atlantis, is a big data acquisition system with a user friendly web based visualization tool.

The platform provides an online interface to visualize the captured data real-time. Atlantis is an online data storage platform where all sensor data is acquired and stored in an online database. The data can be combined with survey data from all kinds of hydrographical equipment. Lastly, the data processing software is capable to acquire, receive, process, display, do quality control and distribute data to the web server for visualization purposes.
