The conversion is described in this document:
You'll want to look at section 220.127.116.11, "Navigation of Image Data". If you're
doing this in Python, you may just want to rely on the calculations in PyProj
(using the "geos" transform https://proj.org/operations/projections/geos.html)
or CartoPy (using the Geostationary projection class
The one caveat for either of these two approaches is that you'll need to
multiply your x,y values by the satellite height to get the proper coordinates
to pass into those projection classes.
Hope that helps,

> I hope this makes sense. Please let me know if you need more information from
