Earth station
"CENTER-1,6Ku"

These stations are used in departmental, general use and fixed networks via retransmitters EXPRESS, EXPRESS-A, LMI in a geostationary orbit within range 14000 - 14500 MHZ on transmission and 10950 - 11200/11450-11700 MHZ on recieve.

Using ES "CENTER-1,6Ku", depending on a complete set the terminal equipment, it is possible to provide:

The organization of a network of the fixed duplex digital directions of a satellite communication;
The demand assignment multiple access mode (DAMA).

Information transfer rate is up to 512 kbps in a fixed directions mode and up to 32 kbps in DAMA.
