MoldATSA, the air navigation service provider of Moldova, has placed an order with Rohde & Schwarz Topex SA for a new voice communications system at its ACC. The new IP-based system uses gateways to interconnect to existing radio stations with analog and IP interfaces, protecting investments made in the past. Using VoIP interfaces in line with EUROCAE ED-137 standards, the new voice communications system for the ACC in Chisinau will be interconnected with the existing R&S VCS-4G systems at the Cahul, Balti and Marculesti airports (systems commissioned in 2011). It will be interconnected with the neighboring airports from Ukraine and Romania by means of MFC-R2 lines.
Besides its use at the ACC, R&S VCS-4G system will also support the communications of the Chisinau control tower and approach. Together with the main operational system, Rohde & Schwarz will provide a secondary voice communications system for simulation purposes in order to recreate the operational scenarios of the main voice communications system.
With the deployment of the R&S VCS-4G system at Chisinau Airport, the entire Moldavian air space will now be controlled using voice communications systems from Rohde & Schwarz. MoldATSA will receive a highly advanced, future-ready system. Voice over IP (VoIP) in line with EUROCAE ED-137 is the upcoming communications technology for ATC, replacing the obsolete TDM based systems. The fully IP-based R&S VCS-4G voice communications system adheres to this standard. Rohde & Schwarz added the R&S VCS-4G state-of-the-art solution to its ATC portfolio in the spring of 2011. The R&S VCS 4G features a fully redundant design with a large number of interfaces to external systems, such as a voice recording system and telephone lines. Due to its unique architecture the system is scalable and can be easily expanded without replacing existing equipment. R&S VCS-4G features already Next Generation ATC requirements such as asset sharing, facility consolidation, geographical distribution and virtual center, supporting the efficiency and safety objectives of global aviation.
