Specific Context : Surveillance modernisation in ECAC is progressing. This includes transition from Mode A/C to Mode S radars as well as implementation of Multilateration and ADS-B systems. Currently more than 1000 WAM/ADS-B ground stations are deployed or committed for deployment by more than 20 European ANSPs. In parallel, the airborne equipage with Mode S/ADS-B avionics is also progressing. The EU Regulation 1207/2011 defines mandatory provisions for equipage and other requirements to airspace Users, ANSPs and Member States. Considering ADS-B equipage, the current regulatory provisions do not apply to all aircraft but only to the ones above 5700kg or 250 kts max cruising speed, thus leading to a mixed traffic situation.
In the context of the transition to a rationalised and modernised Surveillance system, work is ongoing aiming at extending the Surveillance coverage, rationalisation, improving the Surveillance data use, integration within SUR (such as SUR sensor synergies) and with other domains or activities (e.g. NAV, ACAS), data processing, RPAS/UAS etcClick for more info
