VHF System is a part of the Global Maritime Distress and Safety System (GMDSS) in which communications are made on frequencies prescribed by Radio Regulations which regulate the scope and order of usage of radio channels in VHF frequency bands (from 156 MHz to 174 MHz). For VHF maritime radio service 56 VHF channels are used (simplex and duplex channels), among which channel 16 is foreseen for calls and communications in case of a distress and for other communications. VHF channel 70 (156.525 MHz) is used for DSC calls, without regard to the type of call, while other VHF channels are used for other types of communications.
Plovput's VHF system includes the equipment located on three coast radio stations and on 19 sites.
Coast radio stations are connected with each other, as well as with VHF base radio stations by means of a VPN network based on TCP/IP technology.
