Maritime safety

Maritime authorities play a key role in making maritime traffic safe and preventing coastal pollution. The International Maritime Organization (IMO) has defined and adopted (SOLAS convention) a Global Maritime Distress and Safety System (GMDSS).

PRESCOM equipment complies with the safety requirements defined by the International Ship and Port Facility Security (lSPS) code, and sea rescue assistance (AIS, GMDSS).

PRESCOM’s GMDSS solutions enable coast authorities and ports to communicate with vessels by using digital selective calling (DSC), locate them (AIS, ECDIS), manage their movements and ensure physical safety through video surveillance systems (CCTV).

GMDSS DSC equipment for maritime safety: The Global Maritime Distress and Safety System (GMDSS) is a system used by the IMO* and by the SOLAS convention**. By using land and maritime radio services, the GMDSS automatically warns stations on land, rescue teams and nearby vessels, in the event of distress. The GMDSS is used to issue warnings, coordinate search and rescue resources, locate, broadcast general and maritime safety information and to conduct bridge-to-bridge communications.


PRESCOM proposes a GMDSS solution with digital selective calling (DSC) designed for coast authorities and commercial radio communication operators in the maritime zones A1, A2, A3 and A4.

Operating like a telephone, DSC is used in addition to VHF, MF/HF radios. Combining data transmission and voice communication, DSC-equipped radios increase the range of distress calls and can send automatic distress calls, make calls between vessels and be automatically warned about « incoming » calls (including storm warnings and distress calls).
