EarthOrientation.jl

Calculate Earth orientation parameters from IERS tables in Julia.

The package can be installed through Julia's package manager:

pkg> add EarthOrientation

Fetch the latest IERS tables:

using EarthOrientation
EarthOrientation.update()

Get the current Earth orientation parameters, e.g. for polar motion:

xp, yp = polarmotion(now()) # arcseconds

Or the current difference between UT1 and UTC and the associated prediction error:

ΔUT1 = getΔUT1(now()) # seconds
ΔUT1_err = getΔUT1_err(now()) # seconds
