Abstract
Design scheme and implementation for HY-2 ground segment is introduced in this paper. Mission control subsystem is responsible for task scheduling，and system monitor，is nerve center of ground segment. Mixture of C/S and B/S architecture is used for operational and control system (OCS) by its characteristic.Mission control subsystem of HY-2 has three types of scheduling task：real time scheduling task，fixed time scheduling task，data reprocessing scheduling task. In order to reduce scheduling complexity，layered scheduling model is used because of complexity of data processing procedure. Automatic operation pattern is used，making plans in advance，distributed task scheduling，centralized operational system status monitor.
