Data pubblicazione: | 2015 | Titolo del volume in cui è pubblicato il poster: | Solar Physics and Space Weather Instrumentation VI | Curatore/i del volume in cui è pubblicato il contributo: | Fineschi, Silvano; Fennelly, Judy | Serie: | PROCEEDINGS OF SPIE | Numero: | 9604 | Da pagina:: | 96040D | Abstract: | The European Space Agency (ESA) is planning to launch in 2018 the PROBA3 Mission, designed to demonstrate the inorbit formation flying (FF) attitude capability of its two satellites and to observe the inner part of the visible solar corona as the main scientific objective. The solar corona will be observed thanks to the presence on the first satellite, facing the Sun, of an external occulter producing an artificial eclipse of the Sun disk. The second satellite will carry on the coronagraph telescope and the digital camera system in order to perform imaging of the inner part of the corona in visible polarized light, from 1.08 R<SUB>⦿</SUB> up to about 3 R<SUB>⦿</SUB>. One of the main metrological subsystems used to control and to maintain the relative (i.e. between the two satellites) and absolute (i.e. with respect to the Sun) FF attitude is the Shadow Position Sensor (SPS) assembly. It is composed of eight micro arrays of silicon photomultipliers (SiPMs) able to measure with the required sensitivity and dynamic range the penumbral light intensity on the Coronagraph entrance pupil. In the following of the present paper we describe the overall SPS subsystem and its readout electronics with respect to the capability to satisfy the mission requirements, from the light conversion process on board the silicon-based SPS devices up to the digital signal readout and sampling. | Titolo del convegno: | Solar Physics and Space Weather Instrumentation VI | Luogo del convegno: | San Diego, California | Periodo del convegno: | 9 -13 August, 2015 | URI: | http://hdl.handle.net/20.500.12386/24221 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9604/96040D/Formation-flying-metrology-for-the-ESA-PROBA3-mission--the/10.1117/12.2186948.short | ISSN: | 0277-786X | ISBN: | 9781628417708 | DOI: | 10.1117/12.2186948 | Bibcode ADS: | 2015SPIE.9604E..0DF | Fulltext: | open |
