SVOM mission is a Sino-French cooperation satellite which requires high attitude accuracy and platform stability. In order to guarantee the 100s’ observation time, the Relative Pointing Error is required to up to 0.8arcsec/100sec (3 sigma). The Attitude and Orbital Control System (AOCS) is a key element for SVOM mission because of this severe pointing performance requirement. This article describes the AOCS general architecture design for SVOM satellite. First, the main requirements are presented. Second, the key hardware is introduced, including a newly designed sensor, named Fine Guidance Sensor. At last, the AOCS modes design and transfer logic are given.
