System design

Many areas of the world have not yet upgraded their marine radio stations to GMDSS standard.

This is primarily because of the apparent high cost and complexity associated with GMDSS shore station systems.

GMDSS stations do not have to be expensive or complex!

Densham and Associates can design a cost effective GMDSS coast station to suit your needs – be it a simple VHF station or a complete networked VHF/MF/HF system.

 

If you are looking to upgrade your existing GMDSS station, we can supply a new Digital Selective Calling (DSC) system and/or new VHF or MF/HF radio systems.

 

 

We offer a complete turn-key package: design, supply, project management and IMO-compliant GMDSS operator training.

Our systems are reasonably priced, and provide leading edge performance. Typical GMDSS Coast Station configurations are outlined here .

 

Our projects have included:

• Design and installation of a GMDSS Sea Area A1 and A3 Coast Radio Station in Thailand (currently underway).

• Design and installation of a GMDSS Sea Area A3 Coast Radio Station for Mauritius Telecom.
