Validation

The validation work of CASCADE addresses the ADS-B systems and applications, primarily through trials transitioning to deployment. It includes the testing and verification at infrastructure level as well as validation at operational application level.

The CASCADE validation work seek also to make best use of the EUROCONTROL investments e.g. the ADS-B Validation Testbed (AVT), which is the reference platform for the ADS-B validation work in Europe.

Cristal projects

CRISTAL projects have one clear objective: to perform trials in partnership with stakeholders in defined local airspace of Europe (“pocket areas”) where the Surveillance service can be improved and implementation is envisaged. The partnerships with the stakeholders have accelerated the progress from validation to implementation and generated wide stakeholder involvement.  

CRISTAL “ADS-B out” Ground implementation

The project is currently ongoing by CASCADE in partnership with 7 ANSPs, is a cornerstone of the validation work and its clear emphasis is on ground deployment of operational compliant ADS-B and/or WAM systems. The project is a key complement to the airborne deployments ongoing through the pioneer airline schemes and, more importantly, expected through the SPI Implementing Rule. The project covers both Non Radar Airspace and Radar Airspace.

The Air Navigation Service Providers (ANSPs) that participate in this project are:

• AVINOR, Norway
• BULATSA, Bulgaria
• DCA, Cyprus
• DFS, Germany
• HCAA, Greece
• ISAVIA, Iceland and NAVIAIR, Denmark

The projects kicked off in 2009 and will last until 2012-2013 depending on the case.

CRISTAL RAD High Density

In partnership with UK NATS , this on-going project addresses the validation of ADS-B/WAM in the airspace of the London Terminal Control Area, which is one of the most complex and highest density airspaces in the world. It has also studied the future availability of aircraft-derived data (ADS-B ADD application) on the basis of the new standardised technology (ED102A/D0260B). Regarding the latter point it provided recommendations for the availability of Enhanced Surveillance data through active interrogation by an ADS-B/WAM system.

CRISTAL Dual Link Interoperability

This project in partnership with the Swedish ANSP LFV, validates ADS-B in a dual link configuration (1090 Ext. Squitter/VDL Mode 4), in both non-radar airspace (Kiruna) and radar airspace (Stockholm Arlanda).

Pioneer Airline Projects

In parallel to the ground implementation related projects, two pioneer airline projects were launched for ADS-B NRA and ATSAW respectively.
