Rohde & Schwarz and CAAS: research collaboration for space-based VHF voice communications

Rohde & Schwarz and the Civil Aviation Authority of Singapore (CAAS) have signed a research collaboration agreement to conduct a design study on the application and deployment of space-based very high frequency (VHF) voice communications for air traffic management (ATM) in the Singapore flight information region. This technology will enhance aviation safety and enable more efficient use of airspace.

As part of this collaboration, Rohde & Schwarz will conduct an in-depth analysis and study to develop a concept of operations and preliminary communications system designs. The study is expected to deliver innovative solutions for the implementation of space-based VHF voice communications. Bosco Novak, Executive Vice President Secure Communications Division at Rohde & Schwarz, said, “We are proud to have the opportunity to work together with CAAS on the future implementation of space-based VHF voice communications. It is exciting to be invited to develop new communications systems for smart air traffic control operations based on innovative architecture, advanced and trusted technology and efficient operations.”

As a leading air navigation services provider in the Asia Pacific, CAAS has decades of experience managing air traffic flows in one of world’s most complex airspaces. “Space-based VHF voice communications represents the next level of ATM communications capability.  This next phase of collaboration will bring us closer to making space-based VHF voice communications a reality. This technology will enhance safety and facilitate the safe reduction of the separation between aircraft in airspace where ground-based VHF voice communications is currently not available.  It will increase ATM capacity and enable more efficient use of airspace,” commented Mr. Kevin Shum, Director-General, CAAS.

Space-based VHF voice communications involves the mounting of VHF radio communications equipment onto a constellation of low-altitude earth orbit satellites to enable clear, real-time communications between air traffic controllers and pilots over oceanic airspace.
