Супутники і мобільні телефони, що ґрунтуються на міжнародних стандартах, допомагають світові бути на зв’язку. Проте технологія зв’язку, якою ми користуємося на землі, не працює належним чином під водою. Зважаючи на те що вода вкриває майже 70 відсотків поверхні планети, НАТО фінансує дослідження зі створення першого в історії стандарту цифрового підводного зв’язку.

The NATO STO Centre for Maritime Research and Experimentation (CMRE) based in La Spezia (Italy) is working to enhance Allied robotic capabilities at sea and under the sea. Experimentation includes tests with autonomous underwater vehicles (AUVs), such as the one in the picture, and the development of new solutions to empower networks of robots and enable full interoperability among underwater assets. In the picture: an Ocean Explorer AUV being recovered from the NATO Research Vessel Alliance during a sea trial.

- A new era of digital underwater communications 27. Apr. 2017 The NATO STO Centre for Maritime Research and Experimentation (CMRE) based in La Spezia (Italy) is working to enhance Allied robotic capabilities at sea and under the sea. Experimentation includes tests with autonomous underwater vehicles (AUVs), such as the one in the picture, and the development of new solutions to empower networks of robots and enable full interoperability among underwater assets. In the picture: an Ocean Explorer AUV being recovered from the NATO Research Vessel Alliance during a sea trial.
- A new era of digital underwater communications 10. Apr. 2014 Behaviour and capabilities of teams of intelligent robots depend on their capacity to communicate with each other using acoustic signals and to dynamically adapt their missions, without human intervention. However, underwater communication is challenging and until now there was no unique way to do it. In the picture: network of underwater robots during a test of the European Commission FP7 MORPH project, on which CMRE collaborated.
- A new era of digital underwater communications This is where CMRE has played a big role. The Centre has developed JANUS, the first ever digital standard for underwater acoustic communications, promulgated as a NATO Standard since 24 March 2017. JANUS works like a "lingua franca", a baseline common denominator which consists of a robust signalling acoustic method and which allows underwater assets, or networks of assets, to understand each other. In the picture: JANUS spectrogram.
- A new era of digital underwater communications 05. Mar. 2014 Tests of JANUS were conducted using the CMRE Littoral Ocean Observatory Network (LOON), a test bed made by acoustic tripods forming an underwater acoustic network, ideal for low-cost experimentation of underwater communication schemes. In the picture: deployment of one of the LOON tripods in the Gulf of La Spezia (Italy).
- A new era of digital underwater communications Applications of JANUS are limitless. In the operational context, CMRE has already successfully tested the delivery of Automatic Identification System (AIS) data which consist of identification, position, course and speed of ships at sea and Meteorological and Oceanographic (METOC) information to underwater assets using JANUS-standardized acoustic communication. In the picture: the scheme shows AIS data (top box on the right) and METOC (bottom box on the right) information being delivered to a submarine using JANUS acoustic communication.
- A new era of digital underwater communications 10. Jul. 2014 As an example, the Portuguese Navy has been working with CMRE to develop new concepts to support the exchange of crucial information with submarines (typically only available at the surface via radio) such as the location of nearby ships. Digital data exchanges to support rescue operations in case of a submarine incident are currently also being developed. In the picture: in the foreground a Portuguese submarine, in the background the NATO Research Vessel Alliance operated by CMRE, along with the Italian Navy, during an underwater communications sea trial in the Atlantic Ocean.
