Air Navigation Services Of The Czech Republic Transitions To Full Operational Status At New Integrated ATC Center


Air Navigation Services of the Czech Republic has transitioned to full operational status at their brand new, state-of-the-art Integrated ATC Centre (IATCC) in Jenec, near Prague.

An important feature of the new centre is the operational integration of Era’s MSS multilateration and ADS-B system as part of the secondary surveillance coverage around Prague. This achievement marks another important milestone in the pioneering use of next-generation technology by Czech ANS and paves the way for future demands in this rapidly growing airspace. The new ATC centre systems not only support the safety, growth and capacity requirements for the region beyond 2015, but also provide complete fleet coverage today, while supporting the future transition to ADS-B, with a single integrated system.

“Once again, Era has delivered a reliable high-performance component of the Czech ATC infrastructure using its wide area multilateration technology,” said Ivan Uhlir, Czech ANS. “In this project, Era’s distributed timing features have allowed us to deploy receivers flexibly and discretely around the Prague terminal area to establish the coverage that we required. Also as usual, Era’s project and support people turned out to be just as reliable as their technology.”

Czech ANS has a long track record of innovation using Era’s multilateration technology. Czech ANS deployed the world’s first multilateration surface surveillance system in 1999 at Prague airport. In 2002, they commissioned the world’s first wide area multilateration system at the Ostrava Airport, which was type certified against ICAO ANNEX 10 for interrogation and against Eurocontrol radar standards for surveillance performance. The system performed so well that it was operationally certified for 3 nautical mile approach separation. The project was recently recognized with the Development Award at the Jane’s Awards held at ATC Maastricht 2007.

Czech ANS adopted a wide area multilateration strategy with this project after its feasibility studies concluded that MSS by Era would outperform traditional secondary radar with clear cost/benefit advantages.

Era’s latest MSS system at Prague completed acceptance testing in December 2006. The originally requested coverage range of 80 nautical miles has been substantially exceeded out to 120 nautical miles and achieved full compliance with the surveillance parameters of the Eurocontrol standards. The accuracy and resolution ability in the Prague FIR (Flight Information Region) exceeds the capabilities of a traditional secondary radar approach. Further, the first tests have established the suitability of the same system for monitoring the approach to parallel runways.

The IATCC Prague showcases an impressive facility, world-class technology and was awarded the “Building of 2005 Prize” and “The Best Investment of 2005” for the quality of project and investment control.
