 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

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

This is another interesting track (here ''shape=spiral period=1, skip=50)'' on [Windows]XP

[dzach] : [GPSFeed+] outputs [GPS] NMEA 0183, to [TCP]/IP [socket]s connected to it, to [UDP] (multicast too) recipients and to a [serial port]. Any other computer connected to the serial port of the one running GPSFeed+ can receive GPS NMEA sentences. It would be nice if it could simulate an ''input'' serial port on the same computer, so that applications been tested could run on the same computer as gpsfeed+ and use a single serial port.


gpsfeed+ uses a package called carto for drawing gps tracks on geographic space (as opposed to [canvas] space). This package is presented in a separate page here [http://wiki.tcl.tk/13889].

Changed the name from GPSFeed to GPSFeed+ to avoid possible conflict with the name of other products, and to gpsfeed+ (11-3-2005) for aesthetic reasons.
----

[dzach] 11-3-2005: A number of changes (now in version 0.52) besides the aesthetic name change from GPSFeed+ to gpsfeed+:
   * Configuration panel has now 10 entries.
   * Linux and Windows binaries, thanks to [Tclkit]
   * UDP connectivity is now possible with the [TclUDP] package
   * Output monitor
   * User defined NMEA sentences
   * More, here [http://gpsfeed.sourceforge.net/index.html]

And a few screenshots:

Maybe this page should change to gpsfeed+. How is this done?

----

This will interest many people working in [GIS].

----

[dzach] 2005-4-14: gpsfeed+ v0.56 adds a lightweight [http] server to allow web queries, thanks to [minimal tclhttpd].

----

[dzach] 2005-6-27:gpsfeed+ (v0.57 in CVS) downloads, will from now on be hosted on SourceForge at http://sourceforge.net/projects/gpsfeed/
----

[dzach] 2005-8-28: gpsfeed+ (v0.58 in CVS). License change from BSD to GPL. GUI now looks like this:
