Northrop Grumman Corporation's Sperry Marine business unit has released its new Voyage Data Recorder (VDR) Communication Manager software as part of the iFleet suite of optional enhancements for the VoyageMaster VDR system. The VDR Communication Manager permits the VoyageMaster system to transmit packets of telemetry data from ship-to-shore via a communication link. It is designed to work with a variety of satellite services, including Inmarsat-A, Inmarsat-B, Inmarsat-C, Inmarsat-M, Fleet 77 and Fleet 55. To aid in fleet management, shoreside personnel can have automated daily reports -- on the hour, if required -- on data recorded by the VDR, including navigational location and heading, hull stress, bilge levels, tankage, engine status, watertight doors and other shipboard data.
