Voyage Data Recorder (VDR) · Navigation & Bridge Equipment
JRC (Japan Radio Co) VR-3000 — Navigation & Bridge Equipment. As a Voyage Data Recorder (VDR), it is normally installed on the bridge and in associated electronics spaces with inputs from navigation, audio, alarm and machinery systems and with protected recording storage. In that role, its primary purpose is to continuously capture selected voyage and bridge data for later investigation and regulatory review. A full VDR and simplified VDR differ in required input scope, but both depend on reliable data acquisition, time synchronization and protected recording. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
