Issue Date: | 2016 | Volume: | Modeling, Systems Engineering, and Project Management for Astronomy VI | Editors: | Angeli, George Z.; Dierickx, Philippe | Series: | PROCEEDINGS OF SPIE | Number: | 9911 | First Page: | 991105 | Abstract: | ESA's Dark Energy Mission Euclid will map the 3D matter distribution in our Universe using two Dark Energy probes: Weak Lensing (WL) and Galaxy Clustering (GC). The extreme accuracy required for both probes can only be achieved by observing from space in order to limit all observational biases in the measurements of the tracer galaxies. Weak Lensing requires an extremely high precision measurement of galaxy shapes realised with the Visual Imager (VIS) as well as photometric redshift measurements using near-infrared photometry provided by the Near Infrared Spectrometer Photometer (NISP). Galaxy Clustering requires accurate redshifts (∆z/(z+1)<0.1%) of galaxies to be obtained by the NISP Spectrometer. Performance requirements on spacecraft, telescope assembly, scientific instruments and the ground data-processing have been carefully budgeted to meet the demanding top level science requirements. As part of the mission development, the verification of scientific performances needs mission-level end-to-end analyses in which the Euclid systems are modeled from as-designed to final as-built flight configurations. We present the plan to carry out end-to-end analysis coordinated by the ESA project team with the collaboration of the Euclid Consortium. The plan includes the definition of key performance parameters and their process of verification, the input and output identification and the management of applicable mission configurations in the parameter database. | Conference Name: | Modeling, Systems Engineering, and Project Management for Astronomy VI | Conference Place: | Edinburgh, UK | Conference Date: | 26 June-1 July, 2016 | URI: | http://hdl.handle.net/20.500.12386/24912 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9911/1/Mission-level-performance-verification-approach-for-the-Euclid-space-mission/10.1117/12.2233015.short?SSO=1 | ISSN: | 0277-786X | ISBN: | 9781510602014 | DOI: | 10.1117/12.2233015 | Bibcode ADS: | 2016SPIE.9911E..05V | Fulltext: | open |
