ENAIRE provides an air navigation service whose excellence is recognised worldwide. This service is underpinned by the deployment, commissioning and maintenance of an extensive network of navigation systems (radio aids) that support en-route, terminal-area, approach and landing guidance for all aircraft operating in Spanish airspace. Together, these systems make up our Resilient Operational Network (RON).
Navigation
As part of the air navigation services it provides, ENAIRE has also established itself as a benchmark in the implementation of satellite navigation systems. We are, in fact, the second provider in Europe and the fourth worldwide to make Ground-Based Augmentation System (GBAS) technology available to airlines, pilots and airport operators, providing precision guidance during the final approach to the airport. ENAIRE’s investment in GBAS reflects its strong commitment to innovation and to developing new systems that deliver improvements for airspace users.
Since 2020, ENAIRE has been actively driving the development of Performance-Based Navigation (PBN), a concept based on the capabilities of onboard systems. Global Navigation Satellite Systems (GNSS) enable the implementation of PBN in all phases of flight. VOR and DME navigation systems also support the implementation of PBN in en-route and terminal-area manoeuvres. To ensure the safe implementation of GNSS-based PBN flight manoeuvres, ENAIRE has a GNSS performance and interference monitoring network in operation at all our airports. This network is known as RECNET.
At strategic airports, the detection of potential interference in satellite navigation signals has been strengthened by DYLEMA, a system developed by ENAIRE to locate interference sources in real time. Our Resilient Operational Network (RON), comprising conventional radio aids, enables us to continue providing navigation services to airspace users even when GNSS signals are affected by jamming or spoofing.
ENAIRE also hosts and operates, on behalf of the European Satellite Services Provider (ESSP), one of only two EGNOS control centres in Europe, as well as six Ranging and Integrity Monitoring Stations (RIMS). This makes Spain the country with the most EGNOS facilities, all managed by ENAIRE.
To complement the services it provides under the European Space Programme, ENAIRE is also responsible, from 2026 onwards, for hosting the GNSS Service Centre (GSC), a key piece of European infrastructure that serves as the single interface between users and the Galileo system.
ENAIRE is a certified provider of the following navigation services:
- ILS (Instrument Landing System): provides pilots with onboard information for the precision guidance of aircraft during the approach and landing phases.
- GBAS (Ground-Based Augmentation System): a satellite navigation system that provides pilots with onboard information for the precision guidance of aircraft during approach and landing.
- NDB (Non-Directional Beacon): transmits a signal in all directions, indicating the course from the aircraft’s position to the beacon.
- DVOR/CVOR (Doppler/Conventional VHF Omnidirectional Range): provides aircraft with information on the radial on which they are located in relation to the transmitting station.
- DME (Distance Measuring Equipment): enables aircraft to determine the distance from their current position to the radio aid.
