First of all, great package! I have started experimenting with Elm by writing an astrodynamics package. In this field you often want to apply the same transformation to the position...

> I am doing a HUGE rewrite in SatelliteToolbox.jl. Exciting 😎 Let me know if you need/want input. I am getting back in the game... My open-source output suffered quite...

I am working on a pure Julia version of VSOP87: https://github.com/JuliaAstro/AstroBase.jl/blob/master/src/ephemerides/Ephemerides.jl Would that fit the bill? It has the advantage of not needing any external data files (e.g. SPICE kernels)...

So, my VSOP87 implementation is complete and agrees with the original Fortran version in it's native frame (`dynamical ecliptic frame J2000`). They give a rotation matrix to FK5 but with...

Thanks! I have been banging my head against this for a few days now... Here is the information I have collected so far: - There are several different versions of...

I did some benchmarking. Currently the functions in EarthOrientation.jl are a bit slower. - SatelliteToolbox.jl: ~30 ns - EarthOrientation.jl (UT1-UTC): ~70 ns - EarthOrientation.jl (others): ~60 ns But they also...

Okay, new performance results after some tweaks 😄 * EarthOrientation.jl (UT1-UTC): ~38 ns *(edit)* * EarthOrientation.jl (others): ~26 ns

I have a Julia port of poliastro's solver here: https://github.com/helgee/icatt-2016/blob/master/julia/lambert.jl#L27 For now you can just copy-paste it into your code.

> Perhaps you could add in some information, like: which versions of macOS, Julia, BinaryBuilder are you using? Is Docker installed (that's required for doing this on macOS)? Indeed. I...

The issue is macOS-specific. No problems on Linux...
