ATRAK-SIMU (ATC Simulation System)

ICC's ATRAK-SIMU® (ATC Simulation) system is an application developed by ICC in close co-operation with the Air Navigation Services of the Czech Republic (ANS CR). Part of the ATRAK suite of ATC Solutions, ATRAK-SIMU is currently implemented to support simulation and training of ANS CR’s Prague based ACC, APP and TWR operational rooms.

The ATRAK-SIMU system provides all the functionality of ICC's main ATC systems, ATRAK-IMS® and ATRAK-EC/PC® for training and scenario simulation purposes. The main features of the ATRAK-SIMU system are:-

• Virtual time exercise (allows freezing, slowing/speeding up scenarios)
• Data availability control (Datafeeds can be disabled to simulate an outage scenario)
• Runtime-configurable options
• Sophisticated logging facilities

ATRAK-SIMU comprises three core elements for operation:-

• ATRAK Simulation Server
• ATRAK Exerciser Server
• ATRAK Simulation Workstation

The ATRAK-SIMU server replicates the operational ATRAK-EC/PC and ATRAK-IMS data servers and relevant feeds. The Simulator FDP, EC/PC and IMS data processed in background by the ATRAK-SIMU server is then delivered to the corresponding ATRAK-SIMU workstation. The ATRAK-SIMU server is in itself made up of two main parts:-

• Radar Server
• Auxiliary Data Feeder

The Radar server runs as one instance for each group and when started is told to simulate one of the operational radars. The auxiliary data feeder utilises shell scripts and standard Unix tools for file manipulation and data distribution and database command tools to modify the contents of the database. The ATRAK Exerciser Server provides virtual time and separation of positions into the corresponding groups.

The ATRAK-SIMU Workstations replicate operational workstations for ATRAK-EC/PC or ATRAK-IMS and comprise of dual processor workstations supporting the ATRAK digital video interface and relevant ATRAK digital ATC displays.
