[Avionics Today 09-15-2014] Four weeks after Bulgarian Air Traffic Services Authority (Bulatsa) and the Romanian Air Traffic Services Administration (Romatsa) signed a contract with Frequentis to provide more advanced Air Traffic Management (ATM) communication systems and infrastructure for the Functional Airspace Block (FAB) encompassing the Bulgarian and Romanian airspace (Danube FAB), the first system successfully passed its factory acceptance test at the Frequentis premises.
One month after the contract signature in June, the first Voice Communication System (VCS) successfully passed factory acceptance.
The complete Danube FAB program encompasses the VCS and associated radio network infrastructure for ATC centers in Bucharest and Sofia, and at the approach/tower center in Varna and Bulgaria’s Burgas Airport. The solution consists of networked all-IP VCS deployments providing end-to-end VoIP communications between the Romatsa and Bulatsa sites. The future-proof IP-network interoperability, using the European Organization for Civil Aviation Equipment (EUROCAE) Working Group 67 standards, enables safe and reliable communication with all neighboring Air Navigation Service Providers (ANSPs) and also air-ground equipment, according to a statement released by Frequentis.
This is the second European program mandated to Frequentis, an international supplier of communication and information systems for safety-critical control centers.
