本文主要探討通訊星系以對稱型及不對稱型星系設計,任務需求以台灣為中心,模擬半徑1000公里,做軌道高度800及1500公里,並延伸半徑範圍:分別為500 km、1000km、1500 km、2000km、2500 km任務範圍探討;以及利用不對稱方式的高低配單一傾角及利用圓軌道的特性、傾角的變化做星系設計,以衛星高度800公里搭配衛星高度1500公里,分析各不同半徑範圍,探討最少衛星顆數之差異性。
得知軌道高度800km時,傾角30゚、31゚、33゚、 34゚時,滿足任務需求即時通訊,衛星顆數最少為27顆以及軌道高度1500km時,傾角32°到37°時,需15顆衛星即可滿足任務需求即時通訊;當半徑範圍為500km、1000km、1500km時較不適合採用不對稱型來設計,反觀,半徑2000km、2500km時,採用高低配的單一傾角模擬及依據圓軌道特性使傾角的變化下,衛星顆數有減並滿足任務求,即時通訊。 This paper focus on Micro-satellite Constellation for Communication and use symmetry and asymmetry to design. The mission requirement take Taiwan as a center and design radius 1000 km to make the simulation the circular of orbital altitude 800 and 1500 km. And discuss radius 500km、1000km、1500km、2000km and 2500km . Also the attempt use asymmetrical way''s height matches makes the constellations design. As well as the use asymmetrical way''s height matches the sole inclination angle and the use circular orbit characteristic, the inclination angle change makes the constellation design. By satellite altitude 800 km matching satellite altitude 1500 km. Analyzes each different radius scope and difference of the discussion least satellite number.
When orbital altitude 800km and the inclination angle is 30°、31°、33°、34°. The satellites number are 27 to satisfy the requirement. Similarly orbital altitude 1500km at inclination angle 32° to 37°needs 15 satellites satisfy. When the radius scope is 500km、1000km、100km does not unavailability use asymmetry to design, reviews, when radius 2000km 、2500km uses the sole inclination angle simulation which the height matches and based on the circular orbit characteristic causes the inclination angle under the change, a satellite number has reduces and satisfies.
