Ship-based satellite communication station “Centavr-NM-1”
The configuration is designed to be located on surface ships or vessels and will provide reliable communication in any one of the “ship-to-coast”, “ship-to-ship” or “ship-to-mobile node” applications. These stations will support a data transmission rate from 4.8 to 512 kbps.
