Navigational Warnings

Knowledgeable WG members: Jens Schröder-Fürstenberg (GE)

a place to discuss and follow the work

What specifically does the "Navigational Warnings" contain?

• Could they be weather related warnings? (would this overlap with physical environment S-126?)
• What about wave height warnings (oceanological phenomenon)?
• Do they come by radio broadcast, NAVTEX, print, others? (would this overlap with radio services S-123?)
• Will this overlap with navigational services S-125 (notice to mariners)?

Product Specification - new model

The new version of the draft model integrates:

Geolocation

Possible geolocation of each part of the NW’s text: each part of the text can refer to a specific geolocation; this principle could also be applied to T and P NMs, paper chart corrections, description of the approaches in sailing directions or maritime regulations.

Affected Area

(or “caution area”)

i.e. an area surrounding the location of the event subject of the NW. This area is supposed to be used by the ECDIS to notify mariner when the ship’s route cross the affected area (e.g.: the area that corresponds to the range of a light extinguished).

Multilingual texts

as GMDSS NWs must be issued in English and additionally in national language
