本文主要分為氣象與通訊微衛星星系設計及TUUSAT-1A參數管理兩個部份。在氣象微衛星星系設計中，根據任務需求分析衛星之任務特性，決定衛星軌道類型為高度為837公里、傾角為60度的重複地面軌跡圓軌道，模擬結果發現Walker參數18/18/4星系可以每小時拼湊獲取台灣預警區域氣象雲圖。在通訊微衛星星系設計中，採用軌道高度為800公里圓軌道，傾角為22度、30度、35度和40度，計算在不同傾角下對衛星數目的影響，模擬結果發現傾角為35度Walker參數36/9/0星系所需衛星數目最少，可以連續覆蓋台灣半徑2000公里內。
    在TUUSAT-1A計畫中，為切確掌握TUUSAT-1A微衛星整體的發展情況，必須管理各次系統主要參數，最後發現電源次系統的Power Budget在PPM#3時從10.92瓦增大為23.505瓦，預警了電源次系統。

This dissertation contains two parts: the microsatellite constellation design and TUUSAT-1A Technical Performance Measurement. In weather observation constellation design, the periodical circular orbit of 837km and     inclination, which is according to the mission requirement and the characteristics of mission. The calculated result shows that the 18/18/4 Walker constellation satisfactorily meets the mission requirement of piecing the weather warning images of Taiwan on an hourly. 
    In communication constellation design, adopt the circular orbit of 800km. To investigate the influence of orbital inclination to the satellite numbers of the constellation, the orbital inclination in the calculation of Walker Constellation will be substituted by 22, 30, 35, and   individually. The calculated result shows that the minimum number of satellites 36/9/0 Walker constellation, circular orbit of 800km and   inclination, which continuous coverage Taiwan radius of 2000km. 
    To control TUUSAT-1A microsatellite development, must manage the subsystem key technical parameter. The final result warns that the electrical power system of power budget increases from 10.92W to 23.505W in PPM#3.
