Fixed node satellite communication station “Centavr-NM-3”
The station is located at a stationary location near the nodes and provides multiple signal communication up to 8-10 paths over “fixed node-to-mobile node”, “fixed node-to-ship” or “fixed node-to-fixed node” simultaneously.

The station contains:
- Antenna with mounting post
- Hardware configuration (mounted in cabinet)
- Videoconferencing hardware
- Uninterruptible AC power supply
- Encoding hardware for signal security
Rate of information transmission in communication with:
- mobile facilities – from 4.8 to 512 kbps
- fixed node stations – from 4.8 to 2048 kbps
?An extensive selection of earth station configurations provides efficient and high-quality duplex open and closed network telephone and facsimile communication, videoconferencing, data transmission and internet access through C-band transponders on the GSO satellites. Also, a variety of stations can be implemented in either X-band or Ku-band frequencies.
