Aurora is a daughter company of LSE Space who themselves are part of the SSC group. We are a friendly business, operate autonomously and benefit from our relationship within this corporate structure. Aurora is an established supplier of skilled manpower to ESA and in particular at ESTEC and ESAC. Aurora has the opportunity to expand our support to Gaia within the Science and Robotic Exploration Directorate DSRE. Aurora currently has a team of 19 engineers and scientists at ESAC including 5 on GAIA itself. Overview The Gaia mission is planning to map to microarcsecond accuracy 1 of the stellar population of our galaxy that is around one thousand million objects. Each object will be seen about 100 times over the five year mission. The data reduction of the 100 Terabytes of downlinked data is estimated to require a Petabyte storage system. The processing will be community wide effort performed by the Gaia Data Processing and Analysis Consortium DPAC in which ESAC play a coordination role. The ESAC team is forming Gaias Science Operations Centre SOC and is heavily involved in DPAC especially in the overall architecture and the core processing. The core processing includes initial data treatment and the Astrometric Global Iterative Solution AGIS to solve for the many unknown astrometric parameters. The processing is distributed over five locations and ESAC will form the hub for data exchange via the Main Database. This main database will form the input for all processing and will be augmented with the output of all processing to arrive at a new version. The production of processing software for Gaia has started and will continue through operations to final catalogue production in 2019. The SOC maintains core software as well as receiving packages from external entities to be integrated and run in SOC. Specific tasks include Work is to be carried out on the core systems provided by SOC including the Main Database and GaiaTools.
