MARITIME SATELLITE VHF COMMUNICATIONS TERMINAL

The specification defines a set of minimum requirements for a shipboard VHF terminal operating in a VHF satellite communication system. The prime requirements of this equipment are high sensitivity, low noise, high reliability, and moderate cost. A single voice frequency channel is provided for communication over any terrestrial area illuminated by the satellite. Requirements for interface units are also defined to permit teletype, data transmission, and facsimile services. Additional interface units ( filters ) will permit multiplexing voice on the above optional services. In the multiplexing case there will be some loss in voice recognition quality and some reduction in the speed of the optional services. Individual specifications are presented for each major subsystem: Antenna, Preamplifier, and Transmitter Receiver. Each specification is complete and can be used individually to procure the subsystems. Alternately, the specifications can be used as a package to procure a complete system from a single prime contractor. ( Author )
