Update 11/15/2005: Alright, I re-wrote much of the core functionality, and now the device can be started/stopped from the menu bar. I'm almost done getting the configuration dialog completed. Also, I changed the look of the interface a bit. I'm gonna try and see if I can't get some kind of simple vertical progress bar made to show signal strength. You can get a copy of the source through CVS, just poke around on the SourceForge project page ( link).
Update 11/14/2005: The project is now hosted on SourceForge. The new address of this page is http://qgps.sourceforge.net. The page on http://www.acidforum.net/qgps will be removed shortly. I'm working on getting a copy of the initial source code release onto SF, so please be patient. Thanks - Robin.
Here is a link to the source. Warning: it's ugly! I am in the process of re-writing the base code to make it a little prettier and more streamlined. Also, as you'll notice, it unpacks to "qgpsdevice", and compiles as the same. I'm changing that as well. However, it does function. Make sure that you have the Qt libraries WITH THREAD SUPPORT. To compile, type "make" and run it by typing "./qgpsdevice". I haven't run "make install" on my system, so I don't know what'll happen.
QGPS is a small GPS status program written from scratch in Qt. It is designed to work with a NMEA-compliant GPS device that outputs the GGA, GSA, GSV, and RMC strings. Aside from displaying latitude, longitude, and elevation, it also reports satellite signal strength (Signal to Noise Ratio) and positions in the sky using a custom widget (QSatelliteTrack). QGPS uses a custom class called QGPSDevice that inherits QThread, which allows it to read the data from the GPS in the background, while the GUI runs it's event loop, allowing full interaction with the program while listening to the GPS.
Also, I'm sure that there could be some good use of QGPSDevice and QGPSSatelliteTracker outside of this application. Any application written in Qt could use these classes to interface with a GPS, like a wardriving app or a plotter, etc. After I get this app semi-finallized, I'm going to build QGPSDevice and QGPSSatelliteTracker as plugins for Qt, so that others can incorporate them into their apps.
So far, QGPS can:
These are some features that I would like to see / am working on:
And, of course, some bugs I can't figure out yet:
