Description
The Gaia ground segment has proven to be an enormous challenge from the
design, science, technical and managerial points of view. It is expected
that GaiaNIR will observe about eight times more stars than Gaia, and
thus, its data processing will be shattering. From our years of
experience with onboard and onground Gaia data handling, and the lessons
learned, in this talk we will go through the GaiaNIR data pipeline -
from the onboard instrumentation to its catalogue publication. We will
provide some considerations on the onboard data handling requirements,
including compression and downlink, and initial suggestions on the
possible approach and needs for the science ground segment.
