PRESCOM/SECMAT especially offers GMDSS Digital selective calling (DSC) equipment to Coast Authorities and commercial radio communication Operators in the A1, A2, A3 & A4 areas. The solution may be offered both for the GMDSS and the commercial services either in manual and or in automatic for the VHF, MF and HF frequency bands.
DSC radio channels have been dedicated to the maritime VHF, MF/HF bands. They are used to initiate distress alerts, Urgency, safety and routine calls. Subsequent voice and or data communications can follow the DSC on usual distress and or public correspondence radio channels. So maritime mobiles equipped of DSC achieve greater range for distress alerts and other calls and allows to send automatic distress alerts, to makes ship-to-ships calls and to be alerted automatically to incoming calls (incl. sudden storm warnings & distress alerts).
