“The roll-out of CERTIUM VCS to the 22 towers in the Airways New Zealand network offers reliable, fully redundant voice communications for air traffic controllers across a geographically distributed network, as well as a more resilient, standardized platform that can support uninterrupted operations, easier integration and long-term scalability,” said managing director Rohde & Schwarz Australia, Gareth Evans.

Tim Yearsley, head of national engineering at Airways New Zealand, said the system currently used in the Auckland and Christchurch air traffic control centres will be expanded across all 19 towers in the NZ Air Traffic Control (ATC) network, plus three mobile and contingency towers.

“We’re looking forward to the next stage of modernisation in voice communication systems, further extending our IP systems capability for next generation aerodrome control systems, supported by Rohde & Schwarz,” he said.

 
 

According to Rohde & Schwarz Australia head of ATC programs Daniel Wang, Rohde & Schwarz has a long-standing collaborative relationship with Airways.

“The award of this contract demonstrates the strength of our trusted partnership with Airways in the transformation of its nationwide air traffic control communications network,” he said.

“Together, we are delivering a unified, safety-critical communications environment across tower, approach, area and oceanic control operations that enhances operational resilience and supports future growth, aligning with Airways’ purpose of providing safe skies today and tomorrow.”

Rohde & Schwarz was earlier this year awarded a US$4.9 billion contract to overhaul the communication infrastructure for the US Federal Aviation Administration (FAA).
