Genau......

Der BBC-Artikel

bezieht sich auf

"....The ground-based beacons are being retained, despite nearing the 
end of their service life, as they are far less vulnerable to deliberate 
interference from hostile actors compared to GPS."

Kein Hinweis ob LW/HF oder VHF.

DAP (Dublin airport), Cork, Shannon, Connaught DVOR / DMEs as per minimum
operation network requirements
As part of AirNav’s minimal operational network for Navigational Aids 
(NavAids), it was
deemed necessary to keep the DVOR/DMEs as conventional navigational aids 
at Dublin
airport, Cork, Shannon, Connaught. This is necessary to maintain 
alignment with
Commission Implementing Regulation (EU) 2018/1048 Article 6. DVOR/DMEs 
are used to
support en route services (in the event of GNSS outage) and 
non-precision approach
procedures to Shannon, Dublin, Cork and Knock airports.
The existing DVOR/DMEs were installed between 2006 and 2008. The current 
systems are
reaching end-of-life, and some components of the systems are obsolete.

Irland bremst also den vollständigen Übergang auf satellitengestützte 
Navigation (PBN/GNSS) und behält bewusst ältere bodengestützte 
Navigationshilfen (VOR/DME).
Irgendwo ein Bezug zu NDBs?


Hier:

page14:
"The economic study asserts that up to 90% of the existing NDBs and 53% 
of the existing VORs could be decommissioned over the period to 2040."

page24:
"NDB cannot support PBN (Performance Based Navigation) operations, 
avoiding the decommissioning of this technology can only be justified in 
cases where remaining conventional applications required for safety and 
business continuity reasons cannot be supported by a VOR station."
