Various things can go wrong with getting them, so we should arrange to get them ahead of time and enable the modern astropy mechanism for using that cached file.</p> <p>This will require updating astropy to 4.0+, which is currently not safe to do since that would update numpy.</p> INSTRM-1057

Implement offline IERS retrieval and cache.

So if we want to use a single shared cache for all the BEEs, we could put something like <tt>export XDG_CONFIG_HOME=/software/config</tt> in <tt>/software/ics_launch/bin/setups.sh</tt>, I guess.</p> <p>XDG_CONFIG_HOME is part of the "freedesktop.org" convention/"standard".</p> Relates INSTRM-1058 Development Rank 0|02qppo:c Sprint SM1PD-2020 J SM1PD-2021 A 12 Story Points 2.0
