Earth station
Polus-SCC-3,7C

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-3,7C, 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 1024 kbps in a fixed directions mode and up to 64 kbps in DAMA.

The basic characteristics:

Antenna reflector effective diameter	3,7 m (offset)
Polarization	transmission	left-hand polarization
	recieving	right-hand polarization
Antenna gain	transmission	no less 45,2 dB
	recieving	no less 40,8 dB
Range of angular movings of a reflector	at mechanical reinstallation on angle of elevation 0°- 60° at mechanical reinstallation on an azimuth ±60° at autotracking on angle of elevation ±2,5° at autotracking on an azimuth ±2,5°
G/T (angle of elevation 10^o)	no less 21,5 dB/K
Power amplifiers	from 6 to 50 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
