Abstract:
E-navigation aims at increase safety and efficiency of navigation, defining reliable data exchange formats and communication channels between either ship to ship or ship to shore. New technological advancements start from the consolidation of Automatic Identification System (AIS), which is mandatory in some classes of ships for the notification of the position and to send distress signals. In pair with AIS baseline services, additional services are gaining momentum and are available in state of the art equipment, including the handling of sending and receiving Application-Specific Messages (ASMs). In this direction, the VHF Data Exchange System (VDES) standard was recently introduced, to improve on both messaging capabilities and system flexibility (standardizing the use of satellite channels) as well as to allow higher bitrates for application messages with regard to AIS and ASM. In this paper, we reviewed the main characteristics of VDES, then we carried out a technical analysis of
the new communication standard in terms of channel compositions, supported rates, access schemes and latency. Finally, we focus on the performance of two possible future VDES applications, namely “dematerialization” and “towage” through a MATLAB model of the VDES communication channels.
