A partnership approach to the deployment of ADS-B and Wide Area Multilateration (WAM) in Europe
A new information leaflet is available describing the partnership approach taken to the deployment of ADS-B and Wide Area Multilateration (WAM) in Europe.
You may consult the leaflet in the CASCADE documents section.

The Future of Surveillance
08 Feb 2011
The current surveillance infrastructure is mainly composed of mono-pulse (secondary surveillance radar (SSR), SSR Mode-S and primary surveillance radars (PSRs).
Summary of Terminology
08 Feb 2011
Aeronautical Surveillance System is defined in ICAO Doc 9924 as a system that:
- "provides the aircraft position and other related information to ATM and/or airborne users. In most cases, an aeronautical surveillance system provides its user with knowledge of "who" is "where" and "when". Other information provided may include horizontal and vertical speed data, identifying characteristics or intent. The required data and its technical performance parameters are specific to the application that is being used. As a minimum, the aeronautical surveillance system provides position information on aircraft or vehicles at a known time".
Validation
08 Feb 2011
The validation work of CASCADE addresses the ADS-B systems and applications, primarily through trials transitioning to deployment.
Supporting Safety Assessments
08 Feb 2011
CASCADE safety work encompasses a wide range of activities, from international standardisation to support to local implementation.
Information for Aircraft Operators
08 Feb 2011
The “ADS-B Out” capability on board is enabled by transponders interfaced with the relevant avionics systems (such as GNSS, pressure altimeters etc.). Many aircraft have ADS-B Extended Squitter capability already available packaged with the Mode S Enhanced Surveillance installations already mandated for core-European airspace.

Ground Based deployment of ADS-B and WAM in Europe
The ADS-B and WAM deployment in Europe is now ongoing, following three paths:
Strategic and ATM Network Management Context
08 Feb 2011
The vision for ground Surveillance as outlined in the Strategic Guidance in support of the Execution of the European ATM Master Plan (see Surveillance Library section), foresees in en-route and terminal areas the combination of ADS-B with independent Surveillance, the latter provided by MSSR or Mode S or Wide Area Multilateration.
