Rohde & Schwarz in collaboration with the Swiss Skyguide air navigation services organisation, offers the R&S TS6300 test system as an "all-in-one" solution for verifying instrument landing systems (ILS) targeting aeronautical radio navigation systems.

The test systems can measure ILS transmitter systems during a test drive on the runway and simultaneously evaluate the results enabling accurate and reproducible results.

The modular system can be configured to meet individual requirements: from a portable transit case solution to a fully equipped test vehicle with a telescopic mast. The R&S TS6300 contains these core components: the compact R&S EVS300 ILS/VOR analyser, the R&S ILSChecker analysis software and a GPS receiver.

The ICAO Annex 10 and Doc. 8071 standards, from the International Civil Aviation Organisation (ICAO), require airports to perform ILS ground measurement at regular intervals. 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. Rohde & Schwarz designed the R&S TS6300 for these runway measurements.

The R&S TS6300 utilises the R&S EVS300 to deliver reproducible measurements. The R&S EVS300 is a test receiver for ILS/VOR signals that meets the demands of ground measurements and flight inspection systems. The results of ground and air-based measurements can be directly compared, as recommended in ICAO Doc. 8071.

With a measurement rate of 100Hz, 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 60km/h, for example, the system delivers a data record every 17cm. Buildings and other objects (airplanes, cranes, etc.) on taxiways cause signal reflections that distort the ILS signal, changing the measured values. Due to its high sampling rate and excellent measurement reproducibility, the R&S TS6300 can clearly identify these changes.

The R&S TS6300 test system's R&S ILSChecker software analyses the acquired data on site, in realtime, also providing information on whether further tests or corrections are needed. Measurements can be post-processed later in the lab for more detailed analysis.

The R&S TS6300 supports Localizer and Glide Path measurements as required by the ICAO.

The R&S TS6300 test system for ILS transmitter systems is available now.
