After years of development by many parties, including significant input from CML and S3C, the ITU has officially released the standard ITU-R M.2092-1 ‘Technical Characteristics for a VHF Data Exchange System in the VHF Maritime Mobile Band’...
Under the internationally-agreed arrangements for use of the maritime radio frequencies (the ITU Radio Regulations, appendix 18) there are approximately 65 radio channels...
VDES, the VHF Data Exchange System, is the next generation of the well-established and popular AIS system used in millions of vessels globally. VDES encapsulates the current AIS system together with high-rate Application Specific Messages and...
CML Microcircuits has been participating in an international consortium of Marine companies which have just successfully completed trials for a new low cost marine IoT solution. The companies, representing all aspects of the solution ecosystem...
IoT applications are appearing everywhere and one of the most challenging environments is that of maritime applications. Not only do solutions need to work in physically harsh surroundings, the majority of operation takes place out of the range of conventional low cost communications...
When introduced in the mid-nineties by the International Maritime Organisation, (IMO), the Automatic Identification System, (AIS), was aimed at maritime collision avoidance and monitoring of shipping. By continuously broadcasting information over public airwaves using unencrypted VHF radio signals...
The main activity of Emitel is to provide broadcast infrastructure for terrestrial radio and television, but they also provide GMDSS radio-communication services for Polish maritime administration. Therefore Emitel decided to build a VDES test installation that would allow them to learn the basics of the...
We are now in a position to provide a very quick start evaluation enclosure for VDES testing and even base station installation for field trials....
CML Microcircuits and Stone Three Communications have demonstrated a VDES Evaluation Platform that has been used in a number of VDES field trials that have taken place. The VDES1000 module is a Software Defined Radio (SDR) specifically designed to cover the whole maritime radio spectrum;...
The institute of Maritime Technology (IMT) in South Africa has installed the world’s first commercial VDES base station. This will provide services to the South African National Defence Force (SANDF) broader maritime community and industry interested in using VDES new data applications....
The Canadian Coast Gard has forecast that VDES is to become a key medium for ship-shore communication. It was therefore very important for Canada to do its own verification of VDES performance in a real-world situation, gauge performance and investigate any potential adverse effects on...
The Institute for Maritime Technology (IMT), a division of Armscor SOC Ltd., continued South Africa’s strong maritime legacy by installing and operating the first VHF Data Exchange System (VDES) base station in the world. This effort forms part of the Maritime Domain Awareness (MDA) technology...
Introduced in 2002, the maritime Automatic Identification System, (AIS), has been so successful that its use has expanded well beyond its original scope, leading to more and more traffic using the system....
