| 1 The WAM/ADS-B column lists the number of sensors. The configurations and system boundaries for several WAM/ADS-B implementations are complex and site specific. It is therefore not possible to consistently identify the corresponding number of systems | |||||
The Mode-S, Primary Surveillance Radar (PSR) and Secondary Surveillance Radar (SSR) (i.e. Mode A/C) numbers are extracted from the surveillance database of the EUROCONTROL CNS unit.
According to the most recent figures, in Europe there are 526 Mode-S radars, 142 PSRs and 139 SSRs, either combined or standalone. As the allocation and implementation of Mode-S interrogator codes (ICs) require a coordinated approach, every installation of a Mode-S radar is officially registered. The numbers of PSRs and SSRs reported above are not necessarily accurate, as they are based on voluntary reports by the Member States on updates and changes to their surveillance infrastructure. Work on the collection of multilateration (MLAT)/ADS-B stations is still in progress.
The wide-area multilateration (WAM)/ADS-B (wide-area multilateration/automatic dependent surveillance-broadcast) and ADS-B data originate from the database which is maintained by the EUROCONTROL Surveillance and Code Coordination Unit and is based on inputs from stakeholders. The ADS-B and WAM Section coordinates the deployment of initial ADS-B applications and WAM in Europe.
The WAM/ADS-B sensor count only includes sensors mainly used for surveillance of airborne aircraft (e.g. in TMAs or en route). It does not include sensors mainly used for airport surface surveillance (e.g. airport MLAT used for A-SMGCS).
