### Orbit determination from observations
More about Find_Orb (what it does, how to use it, pre-built Windows
executables) at
[`https://www.projectpluto.com/find_orb.htm`](https://www.projectpluto.com/find_orb.htm)
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
the `fo_serve.cgi` program that underlies the
[on-line Find_Orb service](https://www.projectpluto.com/fo.htm).
(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.
You can [click here for directions on building Find_Orb from
the source in this repository.](https://projectpluto.com/find_sou.htm).
As is described at the above link, this project depends on three
of my other projects :
- [`jpl_eph`](https://github.com/Bill-Gray/jpl_eph) (code to read JPL ephemerides)
- [`sat_code`](https://github.com/Bill-Gray/sat_code) (code for Earth-orbiting satellite ephemerides)
- [`lunar`](https://github.com/Bill-Gray/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.
