Abstract

The paper presents the design of the Fine Guidance System of the ARIEL mission. The FGS is one of the two instruments of this mission. The Fine Guidance System (FGS) main task is to ensure the centering, focusing and guiding of the satellite, but it will also provide high precision astrometry and photometry of the target for complementary science. In particular, the data from the FGS will be used for de-trending and data analysis on the ground. The sensor uses star-light coming through the optical path of the telescope to determine the changes in the line of sight of the ARIEL instrument. Optomechanical and electronic part are presented.
