Okay, the regression seems fairly minor, so I won't make a special bugfix release and just fix it in the next version.

Thanks for everyone's patience!

Is this available for Orbiter or is this for Flight Gear ?

It's a stand-alone C++ program - you can use it for whatever purpose you like (I suppose someone could even wrap it into an Orbiter MFD if so desired).

I have benchmarked it against JSBSim, but I have no reason to suspect it would not capture the Orbiter numerics with decent precision as well.

Would it be possible to release some instructions on how to install and use this tool with Orbiter? Maybe a mini tutorial?

Thanks to Face, we're providing a Windows executable. I've not tried it under Windows, but I guess you put it into a directory, put the config file into the same directory, open a command prompt, change into the directory and type something

leo_targeting <configfile>.cfg

all output is either written on-screen or into a file in the same directory (if you want to do plots).

(Since Face evidently got it to run under Win, maybe he can correct anything I'm saying wrong here...) I'm only using it under Linux with gnuplot or xmgrace for doing the plots. Under Windows I guess Excel does plots, gnuplot surely is to be had as well,...

As for what to write into the config file, I have this tutorial series.

I'm not sure what Orbiter provides in terms of the state vector, but I'm fairly sure you can get position in (lat/lon/alt) format, a course, velocity and vertical speed if you want to specify a state.

Yes, this is how I use it. It is a normal Windows command-line application. The *.cfg defines what files are created, and after the program ran through, you can import the 2D files into Excel to do an XY plot diagram. For some 3D animated data I have used Python under Windows with matplotlib and a small script (posted here before).

I forgot to say:

If there's some format/option/... I can add to make this more useful with Orbiter, please let me know. So far most active users of this are on the FG side, so naturally the feedback is a bit biased.
