Via a telescopic mast, the R&S TS6300 from Rohde & Schwarz provides glide path measurement for instrument 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.
