Photometric standard errors are in the milli-magnitude regime. The extreme thermo-mechanical stability of the spacecraft, combined with the selection of the L2 Lissajous point of the Sun-Earth/Moon system for operations, allows stellar parallaxes (distances) to be measured with standard errors less than 10 micro-arcsecond (muas) for stars brighter than 13th magnitude, 20-30 muas for stars at 15th magnitude, and around 300 muas at magnitude 20. Medium-resolution spectroscopic data (resolving power 11,500) will be obtained for the brightest 150 million sources, down to 17th magnitude. Gaia's science data will comprise absolute astrometry, broad-band photometry, and low-resolution spectro-photometry. With a focal plane containing more than 100 large-area CCD detectors, Gaia will survey the sky and repeatedly observe the brightest 1,000 million (one billion) objects, down to 20th magnitude, during its 5-year nominal lifetime. Gaia is the next space-astrometry mission of the European Space Agency, following up on the success of the Hipparcos mission. Standards, will be described and will prove useful for other projects of In the employed PA/QA process, which is based on the relevant ECSS They are needed and fulfill their expectations. GAIA PROJECT RULES PDS SOFTWAREProcedures and mechanisms setup within the consortium to assure thatĭPAC software products and the necessary hardware will be ready when Requires effective quality monitoring and assurance mechanisms and Large group of developers represent a massive development effort which Including a total of more than 400 scientists and engineers. DPAC includes the Science Operation Centre (SOC) atĮSAC and together they constitute the Gaia science ground segment, Scientific community has formed the Gaia Data Processing and AnalysisĬonsortium (DPAC). The ESA satellite Gaia aims to measure the main astrometric parametersĪnd generate an astrometric catalogue of 109 objects with anĪccuracy on the micro-arcsec level.
