Hydronaut H03 underwater station can be used for astronaut training, special IRS projects, medical, biological and psychological research.

Common Tongue

Board Communication System

In Hydronaut, Common Tongue provides communication between the station crew and support team. Also, it allows for live monitoring of crew life functions and of inner atmosphere. The system was designed to allow connection of any other system for research purposes.

People of different needs and skills work together. They need to put down the notes, track deadlines, all relevant changes. Each of us works his/her way, but only together we can achieve big things.


Evironment Inside the Station

The team from the CTU Faculty of Mechanical Engineering in Prague, specifically the Fluid Dynamics and Thermodynamics Department, is, as a partner, responsible for designing and constructing a system for on-line monitoring of the atmosphere within the station. The unique system was designed for long-term monitoring of temperature, humidity and pressure, atmosphere composition and intensity or warmth of the lighting inside the station. The system also monitors board voltage and consumption of electricity. In real time, all data is sent to the control station.

Furthermore, the CTU team will deal with high humidity inside the station. As the already-gathered data show, the relative humidity inside the station is over 95%, with the dew point around 17°C. In practice, this means that vapour condensates on all walls or items with temperature lower than 17°C. This phenomenon brings number of complications. The scientists will aim to decrease the humidity in the station, both by decreasing its production and applying one of the methods of controlled vapour condensation.


Mentoring, Networking and Supporting of Hydronaut

European Space Agency Business Incubation Centre (ESA BIC) Prague creates opportunities for space-related projects and re-purposing space technology. ESA BIC Prague was founded in 2016, and two years later, it was joined by ESA BIC Brno. Both incubators provide the incubation program for up to 2 years. The program includes financial support (EUR 50 000) and professional business and technical guidance.


Light Affects Human Organism

Our pro-cognitive lighting Spectrasol was designed to mimic the sun light spectrum during the day, increasing the serotonin levels of the crew even without natural light. During the day, serotonin is extremely important for correct functioning of the circadian rhythm and sleep. These test results can be used also in real submarines, where the term cabin fever comes from.

Cabin fever is caused not only by confined space, as widely known among the public, but also by missing daylight.

When you aim a ceiling light downwards, it will only support the feeling of a confined space. Such light is not only dazzling, but also creates “cave effect”, making us feel pushed down. When light is aimed upwards, reflecting from the ceiling, the human brain thinks the station is located on the surface, with open hatch and sunlight coming in. Our pro-cognitive lighting imitates the sunlight spectrum, so the daylight effect is almost perfect.


The Impact of Stress on Concentration and Brain Performance

During their stay, the crew is assigned tasks that are carefully monitored and evaluated using the Common Tongue system. Numerus allowed evaluation of changes in behaviour and concentration during Mission One.

Numerus2 in its original version was created as a board game catapulting its author Martin Illek to the Czech Board Games finale in 2012. Then, he put together a team that transferred the game online. Numerus2, the current version for the iOS platform was created by simplifying some game elements from the board game and the original mobile version, cleaning the game environment from disturbing elements, and giving the game an attractive, minimalist visual quality.
