The European Space Agency (ESA) supports the D3TN GmbH in their COLDSUN project. The goal of the project is to develop a buoy to transmit data from an underwater network to the Internet via a satellite network. The innovative communication system offers a cheap and flexible solution to connect underwater networks with centralized infrastructure anywhere around the globe. There, the data can be monitored and analysed.

The prospective buoy system is designed to gather information about the ocean environment. Areas of application include maritime research, off-shore windparks, and fishing. For the next 6 months, ESA supports the development of a prototype to show the feasibility of this innovative communication system. Afterwards, D3TN plans to develop a ready-to-use product based on this system.
