JANUS, the first digital u/w communications standard

摘要

Finally, after 70 years with only the familiar old 'Gertrude' analogue standard, the support of NATO Allied Command Transformation (ACT) has allowed the NATO Science and Technology Organisation (STO) Centre for Maritime Research and Experimentation (CMRE) to develop 'JANUS'; an open, digital standard. It is sometimes hard to get excited about standards, but they are critical enablers for interoperability, and with this new standard in underwater digital communications, we take the first step towards the underwater version of the smartphone and the Internet of Underwater Things (loUT).
