TGNS VOYAGER

Thomas Gunn Navigation Services Ltd have developed an onboard chart management system called TGNS Voyager. The Voyager software is a fully automated onboard chart management system that provides the mariner with a personalised database of charts, publications and Notices To Mariners (NTM's) organised in a convenient folio system.

The Voyager service provides weekly updates to the ships index and Notices to Mariners (NTMs) and Tracings via Internet or Email. The Voyager Data Server compresses the data before sending it to the user to reduce the file sizes to a minimum. The ship only receives the files relevant to its chart outfit, further reducing the file sizes.
