Civil-Military data processing
Challenges for the military
Sharing the right information with the right operational stakeholders, at the right time, is a key principle driving the development and implementation of Air Traffic Management (ATM) data processing systems.
Such systems have to be designed to provide services, information management and data exchange models that are needed to support Air Traffic Services (ATS) operational functions and underlying ATM architectures. These have gradually moved from custom-built point-to-point systems to more interoperable, distributed and flexible service provision infrastructures.
The military need to operate in the same context and, therefore, need to implement adequate data processing systems that are in line with certain Single European Sky (SES) requirements and operational concepts such as OAT Transit Service (OATTS), improved OAT Flight Planning, Advanced Flexible Use of Airspace and Mission Trajectory.
Harmonisation of Military Aeronautical Information in Europe through EAD (HMAI)
Aeronautical information based on paper cannot satisfy all the requirements for an ATM integrated and interoperable system. Therefore, the Aeronautical Information Service (AIS) is required to evolve to a data-centric aeronautical information management (AIM) associated with a modern method of data management.
In this context, the European AIS Database (EAD) is the centralised reference database of quality-assured aeronautical information for airspace users and an integrated AIS solution for service providers. The military need to migrate to the European AIS Database (EAD).
In order to facilitate the harmonisation, standardisation and quality assurance of military aeronautical information, EUROCONTROL has launched an initiative for the Harmonisation of Military Aeronautical Information in Europe through EAD(HMAI).
Activities are ongoing to adapt the Aeronautical Information Exchange Model (AIXM) used by the EAD static database in order to cover specific military requirements.
EUROCONTROL Guidance for the consistency of military aeronautical information publications with ICAO Annex 15 is intended to ensure the conformity of military aeronautical information publication (AIP) formats with the ICAO rule.
SWIM for Military
System Wide Information Management (SWIM) is the ATM Intranet allowing seamless information interchange between all providers and users of ATM information. SWIM supports the exchange of aeronautical, airport, flight, meteorology, surveillance, flow and capacity & demand information. SWIM is based on Service Oriented Architecture (SOA) standardised technologies.
The SWIM –TI profiles, identified in SESAR, include the yellow profile for all exchanges with less demanding Quality of Service (QoS) requirements, the blue profile for real-time or near-real-time exchanges between Air Traffic Control (ATC) centre flight data processing systems, the purple profile for air ground exchanges and the green profile for specific civil-military requirements. The last two remain the subject of research.
“Initial SWIM” represents the first deployment phase, supporting information exchanges built on standards and delivered through an Internet protocol (IP)-based network supporting SWIM-enabled systems. Only the yellow profile is considered to be mature for deployment as things stand, and is currently the subject of further standardisation work.
