At its 56th Session in July, the IMO Sub Committee on Safety of Navigation approved revisions to the World Wide Radio Navigation System, setting achievable requirements for continuity and linking integrity to availability and accuracy.
It was also decided that the issues of a terrestrial electronic position-fixing system as a back-up and user needs for security required further consideration by the (e-Navigation) Correspondence Group with input from other organizations involved.
The delegations of the United Kingdom, Bahamas and the Marshall Islands thanked IALA for its World Wide Radio Navigation Plan, outlining that one of the key elements of e-navigation was a robust electronic position, navigation and timing system with redundancy, in order to provide a viable terrestrial back-up to GNSS.
The development of new symbols for AIS AtoNs was not progressed, as it was decided that a wider policy discussion was needed on their use, in particular for virtual AtoNs.
