Earth station
"Polus-SCC-1,6C"

Used in departmental, general use and fixed networks via retransmitters in a geostationary orbit within range 5925 - 6525 MHZ on transmission and 3600 - 4200 MHZ on recieve.

Using stations of a satellite communication Polus-SCC-1,6C, on a complete set of 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 256 kbps in a fixed directions mode and up to 32 kbps in DAMA.

The basic characteristics:

Antenna reflector effective diameter	1,6 m(offset)
Polarization	transmission	left-hand polarization
	receiving	right-hand polarization
Antenna gain	transmission	no less 38,0 dB
	receiving	no less 34,0 dB
Range of angular movings of a reflector	at mechanical reinstallation on angle of elevation 0°- 90° at mechanical reinstallation on an azimuth ±360°
G/T (angle of elevation 10^o)	not less 14,0 dB/K
Power amplifiers	to 25 W (depending on a required mode)
Inaccuracy of maintenance of the transmitter's output power	no more than ±0,5 dB
Relative frequency instability of the transmitter and HF (first) oscillator of the reciever	no more than ±1x10^-7(during the month)
Radio-frequency equipment — modem interface	by frequency 70 MHz
Availability ratio of the station	0,98
Power supply	single-phase AC line 220 Ā ^+10%/_-15%; frequency 50±2,5 Hz
Power consumption	to 400 W
