Higher Levels of Integra4on  Many onboard devices require similar information

  EPIRB, VHF, Navigation Electronics, Navigation software all require GPS location

 May be desirable to combine several data streams into one for ease of input   VHF DSC data, AIS target data, GPS data could be combined into one data stream

 Might be necessary to convert to a common data rate   AIS data at 38,400bps   GPS data at 4,800bps
