Frequentis AG: FREQUENTIS high-capacity backup ATM system enhances air traffic operations across Denmark

Vienna, Austria (pta011/09.07.2026/10:06 UTC+2)

• ATM automation system now operational, ensuring seamless air traffic control continuity across Denmark's area control centre (ACC) and major airports
• Open platform architecture enables future service integration and long-term system resilience

The Danish air navigation service provider Naviair has successfully deployed and put into live operation its backup air traffic management (ATM) system, based on Frequentis' ATM automation solution PRISMA.

The high-capacity backup system is designed to ensure seamless continuity of air traffic services in the event of a failure of the main ATM system, or during scheduled maintenance and AIRAC (aeronautical information regulation and control) updates. The project delivers a robust and fully capable fallback environment for Naviair's area control centre and approach/tower units at Copenhagen, Billund, and Roskilde airports.

"Our new backup system meets the highest operational and technical standards," says Morten Fruensgaard, Chief Operating Officer at Naviair. "PRISMA gives us the confidence that we can maintain resilient, safety-critical services at all times, and we appreciate the close collaboration with Frequentis throughout the project."

The system is built on Frequentis' open ATM platform, the MosaiX framework, providing high security standards and central management services. It includes a test and validation system (TTC) and a dedicated training environment (TRG) at Copenhagen ACC, as well as remote controller working positions at Billund and Roskilde.

"The transition to live operations marks a major milestone for both teams," says Josef Kutschi, Managing Director at Frequentis Comsoft. "This project demonstrates how a modern and flexible high-capacity backup system can deliver lasting value. We are proud to support Naviair in strengthening the resilience of its ATM infrastructure and look forward to continuing our successful collaboration."

Following an agile delivery approach, the project included three validation phases between 2022 and 2024 and was completed with site acceptance in May 2025. With the system now live and fully operational, Naviair is equipped to ensure uninterrupted ATM services under all circumstances.
