AIS Dispatcher is an AIS data forwarding utility which provides the following features:
AIS Dispatcher performs downsampling of the incoming data feed before sending data to the destination hosts. Downsampling reduces outgoing traffic several times! In particular, for each AIS target (MMSI number) a single set of data must be forwarded to the destination hosts inside a predefined time window. The following picture graphically represents downsampling function:
The time window can be configured between 0 and 300 seconds. 0 seconds means no downsampling. Downsampling reduces the outgoing traffic several times. Downsampling affects AIS messages 1,2,3,4,5,18,19,24 only!
CAUTION: Downsampling is NOT recomended if the AIS information is used for navigational purposes!
EXAMPLE OF USE
The following example illustrates how AIS Dispatcher can forward NMEA messages from a single AIS receiver to AISHub.Net, other destination and local ShipPlotter running on the same windows machine.
