NEW IALA Guideline G1181 for VDES VHF Data Link (VDL) Integrity Monitoring

“VDES VHF Data Link (VDL) integrity monitoring includes the AIS, the ASM, and the VDE, all of which are integrated
in VDES. VDES VDL integrity monitoring is the process of determining whether the VDES VDL is subject to the
injection of errors impacting the reliability and integrity of the data and/or the VDL itself. The purpose of this
document is to provide an overview of the source of VDES VDL vulnerability and propose methods for IALA
members to detect and mitigate the effects of invalid VDL transmissions.”

Stefan Pielmeier, is going to represent the VDES Alliance at the EMSA-ESA VDES Workshop, where insights into the newest developments of VDES will be shared.

The event is going to take place on the 6th of December 2023 at the European Maritime Safety Agency (EMSA) headquarters.

A new RTCM Special Committee 139 to be chaired by Stefan Pielmeier

Radio Technical Commission for Maritime Services will have a new Special Committee 139, chaired by Stefan Pielmeier, the Chairman of the VDES Alliance.

It will standardize the new Maritime Messaging System (MMS) in order to transport digital maritime services that use the formats, authentication, addressing, and trust models of the Maritime Connectivity Platform.

However, instead of existing descriptions such as SECOM IEC63173-2, that would be entirely dependent on IP transport only, the MMS will allow transporting these authenticated services over narrow band transports such as VDES, NAVDAT, ACS, and IP as well in the permanently changing connectivity environment of a ship.
