 What : gpsfeed+, a GPS simulator
 Where : http://users.hol.gr/~dzach/gpsfeed/index.html
 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 or
               a UDP message. It also outputs the same NMEA data to a serial
               port of the PC. Web querying is facilitated by a lightweight
               http server.
