ARTAS 9.0.1 - The community-powered upgrade

EUROCONTROL has just launched a new release of its air traffic management surveillance tracker and server (ARTAS). After more than one year of development and successful trials, the version 9.0.1 brings many new community-sourced features and addresses over 90 issues reported by its users.

Over 25 years ago, EUROCONTROL committed to tackling fragmented European surveillance systems, developed a distributed and interoperable surveillance tracker and server solution to ensure an optimal use of available sensor data. Thanks to a dedicated user-centric approach of the Central ARTAS Maintenance and Operational Support (CAMOS) team, we quickly grew a dedicated community, which helped us direct our efforts and developments.

Today, we are launching a minor version upgrade that addresses much of our community’s feedback. We have introduced some mitigations for ADS-B issues, various improvements for WAM, a monitor of the ARTAS processes as well as some upgrades for cyber security threats.

The 9.0.1 version also brings some major code clean up and refactoring that will easy maintenance and evolution of ARTAS in the future. In addition, the new release introduced several welcome improvements on Requirement Traceability and Quality & Safety processes.

I would like to thank all those who have contributed to this achievement during a difficult year confronted with the COVID-19 crisis.

ARTAS is a European-wide distributed Surveillance Data Processing System (SDPS) offered by EUROCONTROL that is capable of processing surveillance data reports from classical radar, Mode-S, WAM and ADS, providing

its System Users with the best possible real-time air traffic situation, with a high level of accuracy and reliability.


  • is designed to serve a variety of purposes, disseminating relevant surveillance data to a wide range of system Users;
  • is a system under constant evolution to meet the required levels of functional performance;
  • seamlessly integrates Europe’s multi-centre operational environment by addressing SDPS fragmentation;
  • provides efficiency through the common development and provision of baseline software.

System tracks


ARTAS makes use of proven multi-sensor tracking technology to deliver an outstanding level of accuracy and reliability using PSR, SSR, Mode-S, WAM and ADS-B (both Terrestrial & Space-Based) surveillance sources to build an accurate air situation picture for air traffic management purposes.

What differentiates ARTAS from any other SDPDs is the overall concept of a distributed system, consisting of an assembly of identical units that can all coordinate together and act as one region-wide integrated surveillance system.

In addition to this, ARTAS is a one-fit-all solution for EMSOs, flexible enough to fulfil many operational needs.

One feature that permits this is the Tracker Tuning Areas. These are polygons that can be configured to apply dedicated tracker tuning, through parameterisation, thus enabling one ARTAS to satisfy tracking aircraft according to their operational service requirements.

The various surveillance sensors are connected to a Regional Surveillance WAN (wide area network) and the units are also connected to this network. Each ARTAS unit processes surveillance data received on the network and acts as a server, through the EUROCONTROL Surveillance Data Distribution System (SDDS), providing continuous aircraft track data to the ATC units and other systems (e.g. terminal areas, military, flow management units, etc.) that are connected to the network.

The seamless integration of all units allows for the application of 5NM separation minima throughout the covered area, including the transfers of traffic from one ATC unit to the next. 3NM separation may also be applied, following an in-depth operational evaluation of the ARTAS behaviour in local environments.

Data types

In addition to the so-called 'Track-State-vector elements' i.e. position, speed, mode-of-flight etc., which are maintained by the Tracker, the served tracks consist of other data of interest for the System Users, including information relating to flight plans, which are provided by the flight data processing systems of ARTAS i.e. call sign, departure/arrival airports, type of aircraft, etc.


The ARTAS architecture consists of two machines and software services developed specifically for the purpose of the system i.e. the ARTAS Middleware (MW).

The architecture is based on the so-called ARTAS unit - a system that consists of software and hardware resources, designed to meet all the functional and performance requirements.

Software and hardware

The ARTAS software comprises online and offline components, middleware and application software, representing a total of about 2.1 million lines of source code, written in Ada, C, Java, Python and shell scripts.

ARTAS has four groups of main functions computer software configuration items (CSCI):

  • TRACKER (TRK) processes the sensor input data and maintains the latest air situation represented in the Track Data Base
  • SERVER (SRV) carries out the Track and Sensor Information Services, i.e. the management of all requests from Users and the transmission of the relevant sets of track/sensor data to these Users
  • ROUTER BRIDGE (RBR) processes the external interfaces to the Normal Users, the Broadcast Users, the Adjacent ARTAS Units and the Surveillance Sensors
  • SYSTEM MANAGER (MMS) carries out the functions related to the supervision and management of the ARTAS Unit

Each ARTAS unit is hosted at one ARTAS Station (AS) and one MMS-Client Station (MS). A dual ARTAS system consists of two identical computers and their associated peripherals. The internal LAN (Ethernet/Bonding) is part of the system. The TRK, SRV, RBR and MMS-Server CSCIs of each chain are executed on only one node.

Performance and Optimised Tuning

With the latest ARTAS releases, it is possible to go beyond the nominal capacity of 30 sensors and 4,096 system tracks of up to 255 sensors and 32,000 system tracks (subject to validation). In addition, Users have the possibility to customise and fine-tune the system behaviour in each Terminal Manoeuvre (TMA), Inhibit Code Change (ICCA) and En-route areas.

Implementation status

Today, ARTAS tracks close to 90% of European daily flights at 43 air traffic control centres. In total, around 100 ARTAS units are currently deployed or are being deployed.

ARTAS is also being deployed operationally in various Non-EUROCONTROL Member States Organisations (NEMSO), such as Iceland, SA, UAE, Qatar, Indonesia, Papa New Guinea and USA.

Safety compliance and certification

ARTAS was originally developed according to the DOD-STD-2167A, MIL-STD-498 and J-STD-016-1995 standards.

ARTAS and its CAMOS-related processes now comply with the ED-153 Software Assurance Level 3 (SWAL 3). Furthermore, ARTAS processes are compliant with ISO 9001.

Since 2012, EUROCONTROL has been issuing an “EC Declaration of Suitability for Use” for all new ARTAS system releases (Article 5 and Annex III (3) of Regulation (EC) No 552/2004 (the interoperability Regulation) as amended by Regulation (EC) No 1070/2009).

Recent ARTAS releases are aligned with Regulation (EU) 2017/737 (to facilitate Service Providers to create their safety support assessment and/or safety assessment, see section 2.4 Evidence for AMC6 ATM/ANS.OR.C.005 and AMC4 ATS.OR.205 of Regulation (EU) 2017/373). Thus, the EC Declaration of Suitability for Use for new ARTAS system Releases will also satisfy Regulation (EU) 2017/737.

Centralised maintenance and operational support

The Centralised ARTAS Maintenance and Operational Support (CAMOS) Team is a service team at the EUROCONTROL headquarters in Brussels that supports and performs the software maintenance for ARTAS on behalf of EUROCONTROL Member State Organisations (EMSO).

CAMOS in in charge of:

  • support activities at a European level to the numerous EMSO ARTAS systems (both Operational and Pre-Operational);
  • maintenance and preparation of the ARTAS Courses held at EUROCONTROL IANS (Luxemburg) to train ARTAS Users;
  • verification, avoiding any regression, and the release of bug fixes, updates and new ARTAS versions;


  • Provides a Helpdesk service, by answering ARTAS Support Requests (ASRs) raised by ARTAS users, normally for EMSO ANSP representatives.
  • Processes ARTAS Trouble Reports (ATRs) and ARTAS Change Proposals (ACPs), including reproducing ATRs on CAMOS reference platforms and discussing technical matters with Users, Industrial Partners and Subcontractors.
  • Manages the developments performed by Subcontractors. Produces and publishes ARTAS technical documentation (via iCAMOS tool).
  • Participates in factory acceptance testing.
  • Tests and distributes patches and new ARTAS versions delivered by Industrial Partners to ARTAS Users (via iCAMOS tool).

The CAMOS Team delivers, on average, per year:

  • 70 solutions for ARTAS Support Requests (ASR);
  • 70 fixes for ARTAS Trouble Report (ATR);
  • 10 enhancements for ARTAS Change Proposal (ACP);

The CAMOS service does not include hardware support.
