Advanced ATC communications suite

CERTIUM® – Increased safety, security and efficiency

CERTIUM® is a seamlessly integrated communications suite from Rohde & Schwarz that increases safety and efficiency in air traffic communications. As the sole manufacturer, the company provides the entire communications solution from a single source – from the microphone to the antenna. Although each product can be used separately, users benefit the most by combining them with other CERTIUM® products.

In many countries, ANSP infrastructures are considered as critical infrastructure by law and have to be protected accordingly. Rohde & Schwarz pays close attention to the security requirements of ANSP infrastructures. CERTIUM® products use strong security measures to reduce the risk of cybersecurity incidents.

Seamless system operation is key for airspace safety. Rohde & Schwarz uses many redundancy and resilience techniques to maximize the availability of its systems. Quad-redundant architecture with redundancy for centers, systems, networks and radio sites as well as extensive system assurance is a unique combination on the market that is tailored for ATC needs.
