Analyzer Can Verify Aircraft Landing Systems

Munich, Germany: Rohde & Schwarz (R&S) is providing manufacturers and operators of aeronautical radio navigation systems an all-in-one solution for verifying their instrument landing systems (ILS). Its R&S TS6300 is the first test system to allow users to measure ILS transmitter systems during a live test drive on the runway and simultaneously evaluate the results.

The company developed the R&S TS6300 in cooperation with the Swiss Skyguide air navigation services organization. The result is a system tailored to the requirements of air traffic control authorities.

The International Civil Aviation Organization (ICAO) requires airports to perform ILS ground measurements at regular intervals, as defined in the ICAO Annex 10 and Doc. 8071 standards. These measurements provide test engineers working at ATC authorities with important data that can be used to perform preventive and corrective maintenance on transmitter systems.

With a measurement rate of 100 Hz, the R&S EVS300 delivers up to 100 complete data records per second, including GPS time and location information. The R&S ILSChecker software automatically filters the data to match the speed of the test vehicle. At 60 km/h, for example, the system delivers a data record every 17 cm.

Buildings and other objects (airplanes, cranes, etc.) on taxiways cause signal reflections that distort the ILS signal, changing the measured values. The R&S TS6300 test system’s R&S ILSChecker software then analyzes the acquired data on site, in real time.
