Janus sets new standard for underwater communications

14 June 2017

Key Points

  • The Janus protocol is now an approved NATO standard
  • Janus has been extensively tested at sea in exercises involving a number of partners

An underwater communications protocol developed by NATO’s Centre for Maritime Research and Experimentation (CMRE) has become the world’s first internationally recognised undersea digital coding protocol.

Dubbed Janus, the protocol was recently subject of an approved NATO Standardisation Agreement (STANAG). Janus is available to both military and civilian and NATO and non-NATO users, opening the way to what CMRE describes as “a standardised Internet of Underwater Things”.

CMRE, a part of the NATO Science and Technology Organisation (STO), began work about 10 years ago to develop a digital underwater coding protocol that could provide a baseline common denominator for underwater acoustic communications.
