DR3, originally scheduled for the second half of 2021, will include the EDR3 data plus Solar System data; variability information; results for non-single stars, for quasars, and for extended objects; astrophysical parameters; and a special data set, the Gaia Andromeda Photometric Survey (GAPS), providing a photometric time series for about 1 million sources located in a 5.5 degree radius field centered on the Andromeda galaxy. Most measurements in DR3 are expected to be 1.2 times more precise than DR2; proper motions will be 1.9 times more precise. The coordinates in EDR3 use a new version of the "Gaia" celestial reference frame ("Gaia"–CRF3), based on observations of 1,614,173 extragalactic sources, of which 2269 were identified with radio sources in the third revision of the International Celestial Reference Frame (ICRF3). The release dates of EDR3 and DR3 have been delayed by the effects of the COVID-19 pandemic on the Gaia Data Processing and Analysis Consortium. As of 7 September 2020, ESA announced that Gaia DR3 would be released in the first half of 2022.
