Gaia DPCT
The poster shortly presents one of the Italian Contribution to the ESA Gaia
mission, to be launched around October 2012, with a planned lifetime of 5
years.
One of the major challenge of the mission is related to the overall data
reduction that is currently under the development responsibility of a
consortium called DPAC constituted by a large number of European
research institutions.
The overall data processing is distributed
among 6 different centers:
-DPCE at ESAC in Spain,
-DPCB in Barcelona,
-DPCC at CNES,
-DCPG in Geneve,
-DPCI in Cambridge
-DPCT at the ALTEC centre in Turin.

Gaia DPCT
The primary role of the DPCT is to host and operates the Astrometric
Verification Unit (AVU) which is a critical component for:
• the verification of the instruments behavior along the mission
lifetime and their impacts on the received data (BAM and AIM)
• the verification through an independent method (GSR) of the
astrometric data processing performed with the baseline process
(AGIS) at ESAC/DPCE
DPCT will host also:
• the GAREQ system that will process instruments data to detect
light deflection due to quadrupole components of the Jupiter mass.
• the Initial Gaia Source List (IGSL) DB that provide regurarly updates
to DPCE on reference sources.
The DPCT development and operation is a joint effort betwen the science
team of the Astronomical Observatory of Torino and the ALTEC industry
team, in charge of providing the overall HW, SW infrastructure and DB
required for running the scientific SW components
