    • 成功大學科技實驗 (Cheng Kung University Technology EXperimental satellite, CKUTEX) 衛星計畫是由成功大學PACE實驗室所發展。本文旨在描述CKUTEX衛星命令與資料處理(Command & Data Handling, C&DH)次系統之飛行軟體開發過程。其中的討論包括硬體選用之考量、軟體需求分析、軟體分層設計方法、電腦軟體配置項目(Computer Software Configuration Item, CSCI)的解構以及飛行軟體所採用之錯誤偵測、隔離與復原(Fault Detection, Isolation and Recovery, FDIR)方法。此外，本文並說明次系統層級之軟體驗證。由測試結果顯示本命令與資料處理次系統之飛行軟體滿足軟體需求，至此已完成軟體發展之必要程序。

    The PACE lab at National Cheng Kung University has developed a satellite program called Cheng Kung University Technology EXperimental satellite (CKUTEX). This thesis describes the development activities of the CKUTEX Command & Data Handling (C&DH) subsystem flight software (FSW). The discussion includes the hardware selection philosophy, software requirement analysis, software hierarchical design approach, decomposition of the Computer Software Configuration Item (CSCI), and Fault Detection, Isolation and Recovery (FDIR) approach. Furthermore, the software verification on the subsystem level is shown. From the test result, the C&DH FSW meets the requirement and the development of C&DH FSW is completed.
