Solar radius measurements with the SODISM instrument : methods and algorithm developments for the PICARD Payload Data Center

Abstract

The PICARD space mission is scheduled for a launch in 2010. Its payload consists in 3 instruments: SODISM from LATMOS, SOVAP from IRMB (Belgium) and PREMOS from PMOD (Switzerland). SODISM key objective is to measure the diameter and shape of the Sun with an accuracy of a few milliarcseconds (mas), and their potential change during the increasing phase of the current solar cycle. We will present here some simulations and methods developed to make these measurements from SODISM images, and how these ones have been implemented at the PICARD Payload Data Center (PPDC) located at the B-USOC in Belgium.
