Project Presentation

ATRACC (Air Traffic Riga Area Control Centre) is an ATM system for er-route, approach and tower Control of the Riga FIR. The system was designed, produced and implemented by the Swedish company Si ATM for Latvijas Gaisa Satiksme, the Latvian authority responsible for air navigation services in the Latvian airspace. The ATRACC contract was signed in January 1996 and the major part of the system was in operational use as early as December 1998. This successful outcome has been largely due to the two main characteristics of the project model: phased implementation in well-defined steps and strong customer involvement throughout the project. An important asset to the ATRACC project has been the exceptionally active and professional customer involvement.

Summary of Features

ATRACC features some truly pioneering ingredients.

The project is based on high-level requirements, resulting from studies of advanced air traffic control concepts including multiradar tracking, advanced flight plan data integration, predicted flight trajectories, OLDI (On-Line Data Interchange), silent co-ordination and paperless HMI. Especially as regards the latter, i.e. silent co-ordination and paperless HMI, ATRACC is one of the very first projects to have ever implemented these functions in full for area, approach and tower control.

From a functional point of view, the system consists of two main components: a Primary System, providing the full functionality described above, and a Radar Bypass System for use if the primary system should fail.

The system builds on standard commercial off-the-shelf (COTS) products, has an open architecture and can easily be expanded. It comprises 15 working positions intended for operators with different operational roles, specifically TWR (Tower), ACC (Area Control), APP (Approach Control), ARCC (air rescue communication), FDA (Flight Data Assistant), HIST (History, Recording and Playback), OSUP (Operational Supervisor) and TSUP (Technical Supervisor).

Short Term Conflict Alert (STCA)

Customer Swedish CAA, Vikboplan 11, SE-601 79 Norrköping, Sweden
Type of system Safety Net, En-route, approach and tower system for Sweden’s two FIRs.
Activity Development, implementation and installation of Short Term Conflict Alert systems for Mal¬moe Sturup FIR and Stockholm Arlanda FIR.
Completed 1998

The STCA, Short Term Conflict Alert is based on true multi-radar tracking and air traffic statistics.

The STCA was implemented 1999 in the Swedish Atcas systems and in the Latvian ATRACC system in 2001. The STCA system is built on three major components, the Multi Radar Tracker (MRT), the Conflict Alert (CA) and the Radar Operator Position software. The MRT and CA components have been delivered by CelsiusTech Systems.

Key Benefits

  • Stand-alone or integrated system.
  • High performance due to flexibel processing of air traffic.
  • Parameters available for definition of geographical areas (working areas as well as suppression areas).
  • Parameters for exclusion of military codes and areas.
  • Manages up to 13 different radarstations.
