I've put together an open source app, plot2d (http://
plot2d.sourceforge.net), for plotting data (from ASCII files, almost
any delimiter) directly to a compressed image. It uses a simple ASCII
options file. It can also generate statistics for each series.
The program lets you plot GPS time of week and UTC time on the x-axis.
An example data file with GPS time of week as a column can be
downloaded here:
https://plot2d.svn.sourceforge.net/svnroot/plot2d/trunk/examples/gps/PositionError.txt
The first column is GPS time of week followed by error_N (m) error_E
(m) error_UP (m) error_2D (m) error_3D (m).
The project is still in the Alpha development stage. I'm looking for
further design feedback on the software.
What do you think of the target application? Batch/script files for
generating plots+statistics directly to compressed bitmaps.
Would you use this application and why/why not?
What is lacking in the documentation?
If you're keen, some review of the source is always appreciated.

Hi,
just give more examples as what I see is Voltage plot not GPS data.
My friend sdaid that since release of Googvle Earth, Google Maps there
is a little chance to develop any
commercial gps data visualization application.
You can convert your csv file to xml, than to kml and get data
visualized in GE or GM.
Look at Xtraceroute

The options file just needs to be configured a bit further. Check out
the GPS example in
https://plot2d.svn.sourceforge.net/svnroot/plot2d/trunk/examples/
The example image is:
https://plot2d.svn.sourceforge.net/svnroot/plot2d/trunk/examples/gps/PositionError.bmp
I agree for plotting the actual GPS data but this software is useful
for doing some numerical analysis.
The example I gave shows the errors with an RTK GPS solution over time.

Thanks.
Please let me know what is a nature of position error at 18:50 ?
Does it work for any geoposition ?

The position error is outside the window at 18:50 (refer the max/min).
Try changing the ylimits to see the rest of the data.
The position error is calculated with respect to a known reference
position in this case. The math for it can be found at
http://gnsstk.sourceforge.net/geodesy_8h.html#b664109cc9edd99427ec9c141a42b6d9
Position errors can be calculated with respect to known trajectories
as well, so yes it can work for any geoposition if you have a
reference solution of higher order magnitude (say from a GPS/INS
system).
