衛星通訊比起一般通訊網路,無論是在需要大容量之資料傳輸或者是大範圍地區之傳播都有極大優勢。在一些廣大地區,若要架設地面網路線或者無線傳輸都非常昂貴,故衛星通訊非常適合提供這些地區多媒體傳輸之應用。為了得到較好的傳輸品質,衛星天線需能精確指向同步衛星,然而對於移動中之地面站,如汽車、船舶等,因為運動方向改變與本地經緯度的變化,因而造成天線所對準之方位角與仰角需被修改。
本論文之研究內容,在設計一個以智慧型演算法為平台之行進中地面站衛星天線追蹤系統,此系統可以在衛星未被阻隔地方,任何時間,可自動調整天線方向指向衛星,提供不中斷之多媒體服務。運用全球定位系統、陀螺儀與衛星解碼器(同步軌道衛星訊號強度)資訊,透過步進追蹤法與粒子群最佳化演算法計算出變化誤差,操控衛星天線去追蹤衛星得到所要角度。
Satellite communication has many advantages over any other communication’s network whenever the information is targeted at a large population of receivers or when they are spread over large areas. This makes satellite communications to be especially suitable for the provision of multimedia applications in remote areas that would be otherwise very expensive to reach with terrestrial cables or even terrestrial radio links. In order to receive better transmission quality, the direction of the antenna of the synchronous satellite needs to be operated accurately for the ground satellite station moving, i.e. automobiles or ships, etc.
In this thesis, the intelligent-based algorithm is employed to design a tracking system of the moving ground station for GEO (geostationary Earth Orbit) satellites. The system can be applied to multimedia satellite communications anywhere and only for Line-of-Sight communication with satellites. Using the global positioning system, gyroscope and integrated receiver decoder (GEO satellites signal strength) information, calculates out the errors of the change by the step-tracking method and particle swarm optimization algorithm, then the elevation angle and the azimuth angle of the target are tracked efficiently.
