Interference hunting for aviation safety

Pilots and air traffic controllers must have reliable radio equipment. Any failure or any interference can lead to serious consequences. Therefore radio monitoring authorities pay special attention to the frequency band to be protected. As a world-leading manufacturer of radio monitoring equipment, Rohde & Schwarz markets numerous devices and systems for monitoring radio traffic and identifying and locating interference sources.


Equipment and systems for troubleshooting

Radio equipment is the key component in an air traffic control system and has to operate reliably 24 hours a day, seven days a week. As a system planner and integrator, Rohde & Schwarz takes every step to exclude system malfunctions as far as possible and builds redundant components into its systems to render faults harmless if they do occur. Failures or malfunctions of third-party equipment, however, are impossible to preclude or prevent. When they happen, they need to be dealt with swiftly and effectively, and this calls for a precise understanding of the nature and origin of the fault.

The Rohde & Schwarz portfolio of radiomonitoring and direction finding equipment provides comprehensive and reliable tools for gathering the necessary information.

Monitoring antenna



The R&S®HE400 antenna modules provide an unambiguous radiation pattern, allowing users to locate a potential interference source based on triangulation of multiple bearings. In highly reflective environments (i.e. indoors) the last few meters to the target are often found more easily by gradually approaching the transmitter (homing mode).

Wideband monitoring receivers

Wideband monitoring receivers have been specifically designed for signal search, radiomonitoring and spectrum monitoring in line with ITU recommendations. They are equally suited for mobile and stationary use.

Portable receivers

Portable receivers have been specifically designed for radiomonitoring applications in the field. The receiver’s functions and control concepts have been optimized for monitoring tasks. In addition, they can be used for a variety of other applications.
