Because Gaia will perform a continuous all-sky survey at a medium (Spectro) or very high (Astro) angular resolution , the on-board processing needs to cope with a high variety of objects and densities which calls for generic and adaptive algorithms at the detection level, but not only. Consequently, the Pyxis scientific algorithms developed for the on-board(More)
The capabilities of measuring the sky background both on-board of GAIA and on-ground are discussed in relation to astrometric and photometric scientific requirements, and to on-board computing specifications. From the various ways of estimating the sky background during the data reduction it is shown that AF11 would be the more adapted, either using its(More)
We present a high throughput prototype detection framework designed to meet the stringent scientific requirements of the Gaia mission and satisfy real-time and processing resource constraints on board the satellite. A mixed architecture, whose feasibility has been confirmed as part of phase A, is proposed which manages pixel level operations synchronously(More)
