Report on technical characteristics and limitations achieved for VDES

A report on relevant technical characteristics and limitations achieved for the VDES system, including a summary of tests (in laboratory and in real conditions) of the VDES onboard system prototype. Further realistic user cases and categories of VDES devices, including feasibility, path to market, barriers and cost estimates. Input to a draft radiotechnical standard and a draft device specification, including interfacing of a shipborne VDES device.
