1. Implementation Plan
Ronald Drimmel (Project Manager)
INAF – Osservatorio Astronomico di Torino
The GAIA mission The Italian participation in the DPAC Consortium ASI contract I/037/08/0 First Progress Meeting (PM1)
ASI contract I/037/08/0 – PM1 - RD
ASI HQ, Roma, 5 Sep 2008

2. Context of Italian Participation: DPAC
Formation of DPAC in 2006
DPAC “Response to the ESA’s AO for Gaia data processing” approved by SPC in May of 2007.
Top-level DPAC WPs defined
Formation of eight “CUs”
DPAC Executive as top-level executive body
DPAC SRR completed end of 2007
The Italian participation is fully integrated in DPAC.

3. Context of Italian Participation: MLA
Multi-Lateral Agreement between ESA and lead funding agencies signed in February 2008
MLA defines “main deliverables” of signatories.
MLA establishes a Gaia MLA Steering Committee (SC)
MLA SC establishes funding for three new DPAC Project Office positions.
ASI Contract represents first direct funding of the Italian participation in Gaia, and is in-line with the MLA.

4. Italian Deliverables:
SW systems for astrometric verification, including Basic Angle Monitoring device daily processing and the astrometric instrument model.
Italian DPC to host the above systems.
Instrument Model of the payload used in simulations, sensitivity analysis and monitoring during operations.
SW systems for the absolute calibration of the Gaia photometry, together with support for ground-based observations of standard sources and provision of an initial source list.

9. DPAC WBS Organized by CU Each CU having 10 – 15 top-level WPs
Each top-level WPs broken down in numerous sub-WPs
Each WP has a manager who is the “prime responsible”
WPs not assigned to institutes, but individuals (from many institutes) are assigned to WPs.
CU managers responsible for assigning WP management roles and defining CU membership.

16. DPAC Schedule: Organized in 6 month development cycles
ASI Contract covers cycles 5 through 8 (end May 2010).
Next major review: Critical Design Review, June 2009
All DPC Development Plans due
All SW and DPC Test Plans due
All SW Design Documents due
DPAC Operations Plan and End-to-end Test Plan due
End-to-end DPAC testing starts in cycle 9, ends in cycle 10, marking the end of the development phase for DPAC

17. Contract Schedule Start 7/10/2008 (Kickoff) Contract milestones:
KO, 4 Progress Meetings, one Final Meeting
Other than normal reporting, formal deliveries include:
Implementation Plan
DPC Feasibility Study
Italian DPC Implementation Plan (“piano di sviluppo”)
End (latest) 7/12/2008
ASI contract I/037/08/0 – PM1 - RD

18. Phasing the schedules
latest date of Final Meeting after End-to-end Testing starts
Contract does not cover cost of HW that may be needed to support End-to-end testing.
DPC support needed to support End-to-end testing and Operations will be defined in the Italian DPC Implementation Plan. (Necessary input for new funding from ASI!)
To assure continuity in support Italian DPC, the Italian DPC Implementation Plan well before the end of the current ASI Contract! (Not later than PM4.)
There is some motivation to anticipate last Contract Milestones!
