The adventure of microarcsecond astrometry from space: challenges, results and promises of Gaia
Prof. Dr. Sergei A. Klioner (Lohrmann Observatory, TU Dresden)
ESA's space astrometry mission Gaia started its scientific operations in July 2014. Gaia has already delivered an immense dataset of high-accuracy positional and photometric observations which already led to three Data Releases containing high-accuracy data of over 1.8 billion sources. In this presentation I will briefly overview the principles and ideas of space astrometry with Gaia. I will review the challenges of Gaia data processing and highlight some recent results. I will also outline what we have to expect from Gaia in the next several years.
