vakakaaa, aerodrome things for RSBN usage were located on the other side of the runway. They say they were dismantled when the military moved out last July. RSBN (they say) was appliccable when a plane enters the runway from the opposite direction, from the West. This one was East, as I understood. So the plane arriving from the West had to turn around and all.
Dear Alice, there is actually nothing to dismantle in RSBN especially when it is placed in a van. Have a look at location 54:49.7N 32:02.3E (given in XUBS Aerodrom chart 3-164), you will see a special area for RSBN etc. RSBN is not "directional" like PRMG, which serves one runway only (just like ILS), RSBN works in
all directions from
given exact position (just like TACAN, which it resembles). PRMG also seems to serve runway 26, Wikimapia etc shows the antenna on 26 final. My (#596) ideas stem from sukhoi.ru and like others they also are mostly speculative.
