Paper Abstract

METIS, the Multi Element Telescope for Imaging and Spectroscopy, is one of the instruments selected in 2009 by ESA to be part of the payload of the Solar Orbiter mission. The instrument design has been conceived to perform both multiband imaging and UV spectroscopy of the solar corona. The two sensors of the detecting system will produce images in visible light and in two narrow UV bands, at 121.6 and 30.4 nm. The instrument is constituted by several subunits that have to be properly controlled and synchronized in order to provide the expected performances. Moreover, the large amount of data collected by METIS has to be processed by the on board electronics to reduce the data volume to be delivered to ground by telemetry. These functionalities will be realized by a dedicated electronics, the Main Power and Processing Unit (MPPU). This paper will provide an overview of the METIS data handling system and the expected on board data processing.
