METHOD OF COVERAGE EVALUATION FOR CIVIL AVIATION RADIO SYSTEMS WHEN SELECTING THE POSITION OF THEIR PLACEMENT
Presents a method of coverage evaluation for civil aviation ra dio systems, allowing to take into account terrain relief and atm os- pheric parameters of a considered region. Using the digital elevat ion model SRTM allows to evaluate the closing angles for the se- lected position without having to departure to the place for the theodolite survey of the closing angles. The control example f or ra- dar 1L118 shows good conver gence of simulation results and direct measurements. The paramete rs of the atmosphere are esti- mated from the data of long-term observations given in aero climatic reference books. Carrying out of calculations is possible on the average indicators or indicators of the worst month. Considering method can be used to select the optimal positions for rad ar stations, short-range navigation systems VOR/DME, ground-bas ed automatic dependent surveillance stations, and VHF radio communication radio systems to support existing as well as future flight safety requirements.
