The Science Operations and Data Center (SODC) of the ASO-S mission

A ground data analysis center is very important to the success of a mission. We introduce the Science Operations and Data Center (SODC) for the ASO-Smission, which consists of a scientific operation subcenter, a data management subcenter, a data analysis subcenter and a user service subcenter. Themission planning process, instrument observation modes and the data volume are presented. We describe the data flow and processing procedures from spacecraft telemetry to high-level science data, and the long-term archival as well. The data policy and distributions are also briefly introduced.
