PRODUCT NAME
aisdispatcher – AIS NMEA data forwarding utility
CURRENT VERSION 1.2
SYNOPSIS
1. TCP client input:
aisdispatcher -t -h -p -H ,,... [-x ] [-y ] [-D ] [-v]
2. UDP input:
aisdispatcher -u -h -p -H ,,... [-D ] [-v]
3. Serial input:
aisdispatcher -r -d -s -H ,,... [-D ] [-v]
4. input:
aisdispatcher -i -H ,,... [-D ] [-v]
DESCRIPTION
AIS Dispatcher is an AIS data forwarding utility which provides the following features:
- receives AIS data via UDP stream or TCP connection
- performs CRC check and removes duplicated NMEA messages
- performs downsampling of the NMEA stream
- dispatches UDP NMEA streams to unlimited number of destination hosts
