Based on this reality and urgency, the Very High Frequency Data Exchange System (VHF Data Exchange System, VDES) came into being.

[0003] As the third-generation maritime communication system of the Global Maritime Distress and Safety System (GMDSS), VDES is an upgraded and enhanced version of the Automatic Identification System (AIS).
