The Maastricht Upper Area Control Centre (MUAC) established in 2013 the Shared ATS System (SAS), where a virtual centre network solution has been put into operational use, with one air navigation service provider offering shared ATM data services for the benefit of another ATSU in the core area of Europe. With the Shared ATS System the safety, efficiency and cost-effectiveness of a data service solution has been proven.
The ADaaS Demonstrator, designed and developed in cooperation between MUAC and Slovenia Control, is composed of 3 phases: Phase 1: An ATM infrastructure is setup between MUAC and Slovenia Control where MUAC Controller Working Positions (CWP) installed in Slovenia Control are remotely connected to an FDPS instance in MUAC. The communication between the MUAC FDPS and CWPs is using the legacy interface. It is currently implemented and successful shadow operations have been conducted in June 2016. Phase2: The interface between FDPS and CWP is changed to an open interface and the Slovenia Control CWP is connected to the MUAC FDPS via this interface. The OpenCWP interface decouples the ATM data service provider (ADSPs) from the air traffic service units (ATSUs) through an open and standardised service interfaces to foster ADSP/ATSU cross-vendor interoperability. Services include correlation, flight data distribution, flight data management, etc. and has been successfully demonstrated in shadow operations in February 2017. Phase 3: The distributed architecture that allows remotely located data service providers to be completely synchronised is established. The identified solution(s) within the Target ADaaS Architecture have been experimentally established, in order to validate the assumptions and uncertainties of such architecture. Its feasibility has been demonstrated in shadow operations in November 2017
