DSC Controllers - Navigation and Communication
Digital Selective Calling (DSC) controllers are marine communication control units integrated with VHF, MF or HF GMDSS radios. They transmit and receive automated distress, urgency, safety and routine calls using vessel MMSI identification.
ProShipWorks provides end-to-end support to source and supply DSC Controllers for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.
