Neptune VMSPD Hardware Rack for Autonomous High-Speed Data Transmission

The Neptune-VMSPD hardware rack is designed for stand-alone use and operation as part of a high-speed multi-channel data transmission system (HSMDS) on surface ships, mobile facilities and shore-based communication nodes.

The hardware rack provides round-the-clock operation in transmission mode with four independent channels of 500 W nominal power or in power addition modes of two or four power amplification units with nominal output power of 1 kW and 2 kW, respectively.

The hardware rack provides operation in the mode of radio signals reception in the frequency range from 1.5 to 30 MHz with allocation of up to eight independent frequency channels simultaneously and demodulation of single-band telephony, amplitude, frequency and phase telegraphy signals.

The hardware rack provides the mode of transmission and reception of digital data on 1-4 independent frequency channels at speeds up to 9.6 kbit/s in each channel in the mode of single-band telephony with suppressed carrier on the upper side band....
