Store Based Solutions

The water-side VHF communication system developed by Transas is intended to support communication between VTMS operators, sea port administration dispatchers and inspectors, river info service dispatchers, integrated situation centres, pilot service dispatcher centres, coastguard and other users requiring a reliable, multi-user VHF communication system.

Functionality

VTS Radio has a multi-user mode for remote-controlled radio stations, enabling expansion of the system coverage area and increased stability. This minimises the number of certified frequency resolutions as well as supplying extra functions (such as broadcast mode and integration with a VTMS system) for users.

Advantages

    • Connection with remote base stations to expand the system radio coverage area;
    • Connection with any type of radio station (whether operating in marine-mobile service VHF band (156–174 MHz) or in ‘river’ frequency band (300–336 MHz));
    • Connection of MF/HF transceivers;
    • Connection of DSC-modems for message transmission and reception;
    • Connection of remote-control radio stations (E&M tone frequency channels, TDM, TCP/IP) with various communication channels;
    • User-friendly interface based on sensor displays and usual controls (handset, headset, desk mike with talk-listen switch, etc.) with the option to customise the display interface during the installation process;
    • High system reliability due to built-in back-up of key elements;
    • Priority adjustment when using radio stations;
    • Telephone-to-radio communication function;
    • Compatibility with the NaviTraffic/NaviHarbour VTMS hardware-and-software system;
    • Cascading (virtually unlimited) number of users and connected radio stations;
    • System log-keeping of all events with timestamps and registration of all audio calls.

The VHF communication system consists of the following components:

    • Control centre;
    • VHF communication base stations;
    • Remote operator workstations (optional);
    • Telecommunications network.

 

As a rule, audio switching units, the system server and audio registrator are installed at the standard telecommunication rack in the control centre server room. The operator sensor displays are connected via an existing or new structured cable network. VHF communication base stations are connected to the control centre via a telecommunication network (E&M-channels, IP, TDM, etc.). Each base station may incorporate any number of transceivers as well as extra channelling equipment, power supply systems and life support systems. The number of connected base stations is virtually unlimited.
