Protection of Shared Tower for Aeronautical Radio Navigation Station

According to GB 6364-2013 "Aeronautical Radio Navigation Station Electromagnetic Environment Requirements", China lacks the design and construction basis for the protection spacing of shared iron towers. To this end, starting from the interference protection rate of the aeronautical radio navigation station, by establishing a mathematical solution model for the protection distance between the shared tower and the aeronautical radionavigation station, the installation method of the shared tower, the type of the tower and the base number of the tower under a certain line length are carried out. The analysis and the law of the interference protection rate under the influence of these three variables are changed with the distance between the two systems. The results show that the main factors affecting the aeronautical radio range finder station are the installation mode of the shared tower and the number of towers under a certain line length. According to the research results, it is reasonable to set the protection distance between the shared tower and the aeronautical radio navigation station to be within the range of 500m~700m.
