Inmarsat Terminal · GMDSS
Cobham SATCOM EXPLORER 727 Mk2 is identified in the source list as a GMDSS inmarsat terminal. It is normally installed on the bridge, radio station or designated communications area with the antennas, power supplies and backup arrangements required for the vessel's GMDSS installation. Its purpose is to support maritime distress, safety and operational communications using the communications service indicated by the equipment category. The existing database record provides no additional model-specific operating figure beyond the listed designation and category. The exact frequency coverage, satellite service, DSC capability, antenna arrangement and regulatory approval depend on the installed model. The exact model designation identifies communication service, interfaces and approved functions; these must be confirmed from the radio survey records and manufacturer documentation.

What our service work and the manufacturer documentation say about keeping this model running.
Perform operational and self-tests permitted by the vessel's procedures without generating unintended distress alerts. Inspect antennas, feeders, grounding, power supplies, backup batteries and connected navigation-data inputs. Verify station identity, position input, time and configured communication services against approved records. Check printers, handsets, microphones and alarm interfaces where fitted. Maintain software, licenses and service subscriptions required by the installed system. Refer to manufacturer and regulatory documentation for exact test methods, battery criteria and approved servicing.
Keep fuses, handset or microphone accessories, printer consumables where applicable, selected power-supply components and manufacturer-recommended electronic spares. Antenna or feeder repair materials and backup-battery arrangements should reflect the vessel's redundancy plan. Preserve type approval and programmed identity when replacing core units.
