Description

This presentation aims to provide technological and practical lessons we learned from Gaia. We will discuss insights from the data processing, and (systematic) effects of the instrument itself, as well as lessons we learned from processing the necessary auxiliary data like time-transformations (LATT, HATT) and orbital processing and analysis. Furthermore, we will discuss some aspects of what we learned about the influence of the basic angle (in)stability on fundamental physics experiments (like PPN-gamma and other relativistic effects). We argue that care must be taken for GaiaNIR to monitor and stabilize the instrument as much as possible, preferably to an even greater extend than Gaia.
