  This report first describes the status quo regarding the emerging deployment
of very large groups of low-Earth-orbit satellites in the late 2010s, the
concerns raised by the international astronomy community, and steps the
community took to address the issue. We then describe the results of a series
of four conferences held in 2020-21 that considered the impacts of large
satellite constellations as it impacted a number of stakeholders, and how those
outcomes resulted in the establishment of both the IAU Centre for the
Protection of the Dark and Quiet Sky from Satellite Constellation Interference
(IAU CPS) and its Community Engagement (CE) Hub. We finish with a brief
description of CE Hub's initial plans and activities, flowing from the
recommendations of those conferences.
