2. Measurement Equipment
ILS field receiver, Type EVS-200 of Rohde&Schwarz Raw data acquisition at 33 Hz for DDM and RF-Level
Antenna Rohde&Schwarz HF-108 Directivity: gain is 1.2 at 112 MHz, front to rear and right/left ratios 6 dB
In special cases (Position 2 and 8) the opposite LLZ antenna was used as receiving antenna
Notebook PC for recording with ILMA (DFS ILS Measurement Application) Post processing and filtering evaluation by help of Excel for ICAO Filtering at different speeds T[sec]=92,6/V[km/h] typical speed: 60 km/h, in special cases (P5): 10 km/h
