Paper Abstract

The thesis introduces the on-board computer (OBC) software of Chuangxin-1 micro-satellite which developed by shanghai micro-satellite engineering department of Chinese Academy of Science, and illustrates the reliable design for on-board data handling (OBDH) software. The OBDH software adopted some new techniques to improve the reliability. The micro-satellite employed dual-computer, and the standby OBC will take over the management of micro-satellite as soon as the host is failure. The OBC is the core of micro-satellite, and all sub-system of satellite and payload are managed by OBC. To ensure the reliability of OBC, there are some special methods for OBDH software. For standby OBC can take over control of micro-satellite smoothly and resume normal running when the host is failure, some important on-orbit running information of satellite is transferred to standby OBC. These measurements assured the micro-satellite can be resumed to normal running.
