Core processing - Gaia
CU3: Core Processing
| The core processing tasks provided include: |
(a) unpack, decompress, and process the science data retrieved from the MOC to provide rapid (approximately 1 day) monitoring (and feedback to ESOC) of the spacecraft and payload performances at the ultra-precise accuracy levels targeted by the mission;
(b) provide the astrometric global iterative solution;
(c) contribute to key parts of the reduction of the science data and the generation of the final products (pre-processing and core-processing tasks);
(d) periodically re-process raw telemetry, taking advantage of improved calibration data and reduction systems;
(e) assist with instrument characterization and calibration.
