Orbit determination from observations
More about Find_Orb (what it does, how to use it, pre-built Windows executables) at
This project includes code for building Linux, Windows, and BSD
(and possibly OS/X) versions of the interactive Find_Orb orbit
determination software, the non-interactive
fo software, and
fo_serve.cgi program that underlies the
on-line Find_Orb service.
(For a lot of purposes, the on-line service or pre-built .EXEs
may be all you really need.)
Right now, only the Linux and BSD versions can be built with what's posted here. (You can probably build for OS/X, too, but I've not heard any reports on that recently.) I've not gotten around to documenting the Windows build process yet; I just provide the aforementioned pre-built EXEs. Sadly, the Windows builds require the Microsoft compiler, due to an unfortunate early choice to use MFC.
As is described at the above link, this project depends on three of my other projects :
jpl_eph(code to read JPL ephemerides)
sat_code(code for Earth-orbiting satellite ephemerides)
lunar(basic astronomical ephemeris/time functions)
At some point, I'll probably document the build procedure for Windows, but it does appear that most Windows users just want pre-built executables.
