The Marine Data MD100 enables coastal stations, or boats sailing in busy shipping lanes, to receive AIS (Automatic Identification System) information being transmitted from Class “A” transponders as fitted to vessels over 300 tons, and non-mandatory Class "B" transponders as fitted to small commercial and leisure craft.
Connected to a compatible on board PC running a Navigation Program, or dedicated marine Chart Plotter, the information can be displayed on screen giving the skipper or harbour authority a visual interpretation of the name, position, course and speed of vessels within VHF range. This information is updated every 3 seconds to 6 minutes depending on speed and rate of turn, enabling the track of the vessels in range to be plotted.
