Together with Galileo, EGNOS is Europe’s other satellite navigation system, which is today in routine use at around 367 European airports and helipads. Through the use of EGNOS, satellite navigation signals become sufficiently accurate and reliable for all kinds of ‘safety-of-life’ uses. These airports and helipads are utilising EGNOS-based LPV-200 approaches, short for ‘Localizer Performance with Vertical guidance – 200 ft (60 m)’. The freely-available EGNOS service requires no ground equipment whatsoever, replacing the radio guidance beamed upward by traditional CAT I Instrument Landing System (ILS) infrastructure with no decrease in performance.
