"Ku"-band Earth stations
Stations of the Ku-band are applied for work in satellite systems of
communication in a mode of multistation access with frequency division (FDMA)
via retransmitters in a geostationary orbit - "Gorizont", "Express",
LMI, Eutelsat and (or) in a demand assignment multiple access mode (DAMA):
