Class SimGPS

java.lang.Object
  ecologylab.generic.Debug
      ecologylab.sensor.gps.GPS
          ecologylab.sensor.gps.SimGPS

All Implemented Interfaces:

gnu.io.SerialPortEventListener, java.awt.event.ActionListener, java.util.EventListener

public class SimGPS
extends GPS
implements java.awt.event.ActionListener

A simulated GPS that uses a text file containing NMEA sentences to drive a GPS-based application. Usage: Instantiate with a text file containing NMEA sentences. Like normal NMEA setences, each line should end with \r\n. Register one or more GPSDataListeners to listen to it. Call either start w/ the number of milliseconds between sends. -OR- Call sendSentence (to handle it interactively).
