maintain and the least reliable. However, it is
not expected that rotational systems will
disappear altogether, unless the substitute
systems can supply full 360° coverage.
To meet this trend and also meet our
customers’ needs, Cobham is making
improvements to existing hardware for
increased frequency bandwidth, power
handling or mechanical improvements.
Are there any current trends or new
technologies that are important
to Cobham and the sector?
The expansion of drone technology has been
good business for Cobham’s rotary joint,
pedestal and waveguide products since many
drones use rotational radar and
communication systems and Cobham offers
a wide range of solutions for this technology.
This includes multi-functional pedestal
assemblies, including waveguide and coaxial
rotary joints, slip rings and media joints.
How do you think the ATC sector
will change in the future?
Based on the rate of expansion in satellite
technology, I expect ADS-B to slowly replace
traditional ground-based radar and
eventually transform the air traffic control
system into a versatile, user-based network
resulting in more efficient air routes,

scheduling and capacity. However, current
ATC systems will still remain viable well
into the future, albeit in a repair and
maintenance mode as ADS-B becomes more
Is there any best practice or
standards-related information you
would like to communicate?
Cobham’s focus is people-oriented and
mission driven and we work closely with
customers to address customer requirements.
We are well-suited to meet ATC
manufacturers’ needs due to our vast
experience, technical excellence, component
database and manufacturing infrastructure.
Especially within the rotary joint business, we
have the most experienced manufacturing
and engineering staff in the rotary joint
business coupled with the largest design
database in the Industry.
What are the plans for the future?
It is not anticipated that transformation of
the ATC infrastructure will involve an
upgrade or expansion of the current rotary
joint technology. Cobham remains focused
on providing timely support for the ATC
industry in the repair and refurbishment of
not just rotary joints, but all of the microwave
components we supply to the industry. v
