GPS
Class ProcessNmeaData

java.lang.Object
  PamguardMVC.PamProcess
      GPS.ProcessNmeaData

All Implemented Interfaces:

Annotator, PamObserver

public class ProcessNmeaData
extends PamProcess

Author:

Doug Gillespie PamProcess that subscribed to the AcquireNmeaData processes output data block, selects just the interesting stuff in the GPRMC string and creates a new data block with the string data unpacked into more usable doubles.
