Class PVTDataPacket

java.lang.Object
  org.jscience.devices.gps.garmin.GarminPacket
      org.jscience.devices.gps.garmin.PVTDataPacket

All Implemented Interfaces:

IPosition, ITime

public class PVTDataPacket
extends GarminPacket
implements IPosition, ITime

This class encapsulates the PVT (Position, velocity and time) packet. After receiving a Cmnd_Start_Pvt-packet, the GPS will continually transmit packets of the PVT-type.
