ASR-NG® : Future Proof Technology for Safe Skies

CassidianWithout a doubt  technology has changed tremendously over the years, and as a consequence, customer  requirements have become more and more demanding. In addition, competitors entered the market with new radar concepts with the main purpose of fulfilling the needs of the users. As near-miss incidents frequently occur in today's busy aerospace, state-of-the-art Air Traffic Control Radars have to deliver an outstanding exposure and protection from potential threats to the smallest aircraft such as ultra light gliders as well as the largest passenger aircraft.

Nowadays the airspace is  divided between civil and military users, general aviation traffic as well as  leisure time flights. In the challenge to meet  all detection performance and safety requirements, one needs  to provide more powerful surveillance sensor solutions.

Having the ASR-S (Airport Surveillance Radar) as its predecessor, the ASR-NG® takes a step further in terms of technological advances and extreme sensitivity capabilities, thus making an important  contribution  to the efficient use of airspace.


From acquisition to life support: Maximum performance, reliability & longevity

With the aim of fulfilling both civil and military needs, Cassidian's product philosophy is targeted towards cost effectiveness, reliability and last but not least, user satisfaction for airspace safety. Our goal  is to connect and build strong relationships with our customers by offering them  excellent services and successful  execution of projects.

Above it all,  the ASR-NG® system offered by Cassidian  is one of a kind , reliable, affordable  and least but not least high performance ATC radar. In addition to incorporating one of the only AIMS 03-1000A certified secondary surveillance radars available, its algorithms, methods of signal processing and subclutter visibility result in extremely reliable detection and tracking performance under the most challenging weather conditions, over heavy clutter including wind farms, and against the smallest targets including UAVs, gliders, and ultra light planes.   

Our product  has been specified, designed and developed  in order to meet  the highest international safety  standards and requirements.  

The system is certified by the German authorities to be compliant with RTCA DO-278, ED 109 AL4, EATMP SWAL3, IEC 61508 SIL2 and hence guarantees inherent functional safety.
