Edit: Didn't catch this until I read Enclosure 6 carefully:
"or to convey an aid to navigation
that has yet to be charted."
So sounds like Denver is right, but you have to read the fine print. Everything about creating the virtual ATON said nothing about it being only virtual until a physical one was in place.
I think they are interested in virtual ATONS.
I can't find the LNM that shows it has already been deployed, but go to
48.11306 / -122.6612
and you will find a virtual ATON on a live AIS
– ADMIRALTY INLET - Virtual AIS position Puget Sound
Traffic Separation Lane “SB” to be created
The U.S. Coast Guard will be creating a Virtual AIS (Automatic Identification System) identifier at the following position in Admiralty Inlet:
Traffic Separation Lane V-AIS “SB” (LLNR 16502) in position: 48-06-47.016N 122-29-40.428W
The Virtual AIS message will not correspond to any physical buoy but will be broadcasted from an AIS Base Station to coincide with the position listed
above. Vessels with AIS capable systems will be able to see the symbology and other information on their displays. For more information about AIS,
Mariners should read enclosure (6) to this Local Notice to Mariners and/or go to the U.S. Coast Guard Navigation
