Challenge Today’s intensive use of the radio frequency spectrum by very different users creates more and more conflicts of radio signal interferences. Normally, if Radio Frequency Interference (RFI) is identified during flight inspection, the task of the flight inspection crew ends. A special trained ground crew is brought into place for the complex task of locating the RFI source. Typically this is performed by ground based equipment in fixed, portable or mobile installations. If the RFI analysis equipment must be transported to the area of interest first, this could take a lot of time....

Interpretation AD-ARLOC II Equipment AeroFIS® Direction Finder Software The AD-ARLOC II is based on the following The control of the AD-ARLOC II is fully equipment: integrated into the AeroFIS® Software: • Remote control of Spectrum Analyzer • Recording of Spectrum Analyzer graphs for time synchronized replay • Recording of interference audio (MP3) • Automatic Spectrum Analyzer antenna switching • Remote control of Direction Finder (DF) • DF antenna bearing error compensation (antenna calibration) • DF bearing indication to pilots • Algorithms for interference localization • Visualization...

Visualization Presentation on Map The DF flight track and the bearing results are shown on a simplified Lat/Lon Map in the AFIS software and exported into other maps, e.g. Google Earth. The green line shows the flight track and the blue dots show calculated locations of RF source online while the flight. Currently the best estimated position is presented in Lat/Lon coordinates. Flight track and estimated coordinates of the RF source exported into other maps or satellite views, e.g. Google Maps We keep you on the best path! Aerodata AG ∙ Hermann-Blenk-Straße 34-36 ∙ 38108...
