The vessel monitoring system (VMS) is a satellite-based( Inmarsat-C, Iridium or Inmarsat-D+ ) monitoring system which at regular intervals provides data to the Data Center on the location, course and speed of vessels.
MVMS sends the following standard data to the Data Centre:
- Identification of the ship
- Ship’s current geographical position
- Date and time of ships position
- Ship’s speed and course at time of position report
