    Abstract: 本文從事星系設計分析,主要針對台灣地區需求從事氣象觀測星系設計與通訊衛星星系設計。在氣象觀測微衛星星系設計中,任務需求定?覆蓋從東經60度至180度,北緯0度至60度之氣象觀測。分析結果以軌道高度837公里、傾角60度的重複地面軌跡圓軌道,應用Walker delta pattern方法發現以18/18/4星系可以最少衛星數目達到每小時拼湊獲取預設區域之氣象雲圖。在通訊微衛星星系設計中,採用軌道高度?800公里圓軌道,地面水平仰角5度以上,分析傾角?22度、30度、35度和40度,計算不同傾角對衛星數目的影響,模擬結果發現傾角?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公里內之即時通訊。
    In this paper the weather observation and communication satellite constellation design applied to Taiwan area is presented. The weather observation area was defined as 60°E to 180°E and 0°N to 60°N. The mission requires acquiring at least one weather image per hour covering this observation area. The walker constellation analysis is employed to calculate the minimum number of satellites for this mission requirement. The result showed that the 18/18/4 constellation satisfactorily meets the mission requirements. In the communication satellite constellation design, the Walker analysis is also employed with assumed angle of elevation greater than 5 degree and 800 km circular orbit. The results showed that minimum number of satellites of constellation is 36/9/4 with an inclination angle of 35°, which satisfy the continuous coverage of the region of 2000 km radius with center at Taiwan.
