Driver for outputting an ASCII NMEA GPGGA string, output every Qinsy update. The update-rate can be defined as system property in DB Setup.
The latitude and longitude fields in the string refer to the position of the selected "Position Node".
The height field in the output string contains the height difference between a "Reference Node" and a "Target Node", which could differ from the "Position Node".
The appropriate output nodes must be selected before the driver starts cycling.
After going online with the Controller for the first time, select the "Change Nodes..." option in the output driver's dialog and select the appropriate computation and nodes.
