本文主要是針對TUUSAT-1A微衛星之細部設計，使用系統驗證軟體TUUSIM(TUUSAT-1A SIMulator)對任務做模擬分析。由微衛星的概念介紹、TUUSAT-1A任務與架構為前導，在瞭解微衛星的基本架構後，進而說明微衛星各子系統細部設計，包括系統設計與初步設計，例如系統需求、硬體等設計，並對每層的系統配製作詳細的說明。接著為了驗證TUUSAT-1A子系統設計與效能，使用研究團隊自行發展的驗證軟體TUUSIM，在整合熱控程式後，對姿態、熱控、電源與通訊四個子系統作任務模擬分析，將模擬結果與系統細部設計作討論。 This paper according to critical design of TUUSAT-1A subsystems uses simulator to verify the mission requirements. By the introduction and concept of the micro-satellite, the mission and frames TUUSAT-1A, after understanding the basic overhead construction of micro-satellite, then explain critical design of micro-satellite, including system design and the preliminary design, for example system requirements, hardware and so on. Then we give the detailed explanation to each tray configuration. For verification the TUUSAT-1A subsystem design, using the software TUUSIM that developed by research team, after combining with thermal programs, to run mission simulation of attitude control, thermal control, electrical power and communication subsystem, finally discusses the result with critical design review.
