ATRAK-BYPASS (ATC Radar Fallback System)

ICC's ATRAK-BYPASS (ATC Radar fallback 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-BYPASS is currently implemented at ANS CR’s Prague based ACC, APP and TWR operational rooms.

ATRAK-BYPASS® is a standalone radar fall-back system providing back-up Air Situation Display functions as well as Flight Data presentation in case of fail-over of the main ATC Executive system. ATRAK-BYPASS is configured with totally independent radar feeds from the Executive system ensuring total system continuity in the event of a failure.

The ATRAK-BYPASS system in fallback mode can be used as:

• A fully functional ATC executive system or as a planning control and fall-back system alongside 3rd party executive systems.

• A fully functional ATC system for the duration of executive system unavailability.

ATRAK-BYPASS works in union with 3rd party ATC systems such as Thales Eurocat 2000, as well as the ATRAK-IMS Information Management System.

ATRAK-BYPASS comprises two core elements for operation:-

• BYPASS Server
• BYPASS Workstation

The ATRAK-BYPASS server provides the core Information Data Processing system (IDP) and Flight Data Processing system (FDP) integration when in standby or fallback mode but takes its feeds from totally independent sources to those of the live Executive system. Data is processed in background by the ATRAK-BYPASS server and is then delivered to the corresponding ATRAK-BYPASS workstation.
The system consists of 2 ATRAK servers with Quad processors. The systems are backed up to the main ATRAK-EC/PC Server environment but are configured as separate standalone systems on an independent network to the rest of the Operations user traffic.

The ATRAK-BYPASS workstation comprises of a dual processor ATRAK-BYPASS workstation supporting the ATRAK digital video interface and ATRAK digital ATC displays. The displays and video interfaces for ATRAK-BYPASS support the ATRAK 30” display which is extended to operate remotely from the workstation via the ATRAK Desktender.

ATRAK-BYPASS can be provided as part of the complete ATCsolution. The ATRAK-BYPASS Enterprise Series solution includes a Unix based enterprise server, integrated database and high performance display processing. All hardwareis selected specifically for the application, configured and optimisedto achieve the highest levels of performance and reliability. Workstations can optionally be extended from the Controller Work Position (CWP) by up to 1000 metres using the ATRAK Desktender.
