 Description : GPSFeed is a software GPS simulator, a utility that feeds the PC 
               with continuous GPS data as if it were traveling in a car or airplane. 
               NMEA 0183 GPS sentences are sent to the application through a socket 
               (TCP/IP) connection. It also outputs the same NMEA data to a serial port 
               of the PC.

GPSFeed looks like this in Linux KDE, running ''spiral'' track shape.
