Motion-based Consistency Audit of the Onboard GNSS Reference Reported by the Static AIS Data

Kurzfassung

The Automatic Identification System (AIS) is widely used for reporting vessel movements and broadcasting additional information related to the current voyage or constant parameters like the IMO number or the overall dimension of the hull. Since the dynamic AIS data is shared mostly without human interaction and is not flawless, the static AIS content edited manually may also be highly exposed to errors and mistakes due to the predominant human factor. In this work a simple vessel motion pattern approach is introduced to determine the probable foredeck/afterdeck location of the GNSS reference used by the AIS transponder, and to compare it with the hull parameters obtained from the static AIS data, in order to find the observable blunders in the static AIS configuration of the mount point of the GNSS reference antenna.
