Abstract:	近年來，LEO 衛星在諸多方面發展，防災、探勘等。為了接收衛星回傳資料，需要地面接收，早期多採用定點式，而隨著天然災害等不定期影響，轉往移動式地面站。因此本文開發一行動地面站，將裝置安置車頂、亦或固定表面。使用者可以透過電腦選擇接收開放衛星。本文內容將介紹電磁波、座標系統、六元數、軌道預測方式，並說明自行開發機構設計、電路模組、433MHz 收發機與十字型指向魚骨天線，最後透過實驗，說明模組校正，伺服機調整，與最後追軌結果。;In recent years, LEO satellites have been developed in many fields such as forecasting of disaster and exploration. In order to receive the data of satellite, ground station is required. In the past year, fixed ground stations were used, but with the occasional impact of natural disasters. It was improved to mobile ground stations. Therefore, this dissertation develops an mobile ground station to install the device on the roof of car or the fixed surface. Users can choose to receive open satellites through the computer. The content will introduce the electromagnetic wave, coordinate system, Keplerian element and the methods of orbit prediction. It also explain the self-developed mechanism design, the circuit of module, 433MHz RF Transmitter and cross-shaped yagi antenna. In the end of the dissertation will explain the calibration of the function of module, servo adjustments and the result of tracking through a series experiment.
