ENAIRE is a global pioneer in directing its R&D efforts toward cooperative surveillance, enabling the use of the most advanced air-traffic-surveillance systems, such as ADS-B and Mode S radars, depending on the specific operational need.
Surveillance
By introducing ADS-B systems, ENAIRE provides surveillance in areas not covered by radar and complements existing coverage, optimising the surveillance network from an economic, environmental and service-quality perspective.
Mode S supplements traditional radar surveillance, allowing better identification of aircraft, reducing radio-frequency congestion and providing air traffic control with additional information on an aircraft’s short-term intentions.
In oceanic areas, ENAIRE provides ADS-C surveillance based on FANS technology, allowing traffic to be monitored via satellite data link.
ENAIRE operates a network of surveillance systems for en-route, aerodrome and surface environments to detect aircraft, determine their position and supply this information to controllers, covering all Spanish airspace:
- PSR (Primary Surveillance Radar): detects non-cooperative targets in en-route and TMA environments.
- SSR (Secondary Surveillance Radar): detects cooperative targets in en-route and TMA environments, including Mode S.
- SMR (Surface Movement Radar): detects non-cooperative targets at airports.
- MLAT (Multilateration Systems): detects cooperative targets in TMA (WAM) and airport environments.
- ADS-C (Automatic Dependent Surveillance Contract): contract-based dependent surveillance.
- ADS-B (Automatic Dependent Surveillance Broadcast): broadcast-based dependent surveillance.
With this advanced infrastructure, ENAIRE provides the following certified services:
- Provision of data from primary surveillance radar (PSR).
- Provision of data from secondary surveillance radar (SSR). Mode A/C and Mode S.
- Provision of data from surface-movement radar (SMR).
- Provision of data from multilateration (MLAT) systems.
- Provision of data from Automatic Dependent Surveillance (ADS). ADS-C and ADS-B.
