According to the standard scheme, the RSBN is installed within a designated zone. This zone is bounded by parallel lines 300 m and 600 m from the runway centerline, as well as a circle with a radius of 1200 m, centered at the Aerodrome Reference Point (ARP).
At a suitable point in the RSBN placement zone, the surveyor determines the exact geographic coordinates of this point, then the RSBN is positioned so that the axis of the azimuth antenna is exactly above the selected point.
