    Abstract: 為了進行規模面積搜尋衛星酬載,本研究藉由不同的無線電通訊系統的探討與比較,總結系統的設計需求。再以無線電的理論為研究背景,借以規劃出系統的規格構想與實現需求。
    而為實現搜尋網路系統的開發,將系統將由地面站、及轉發站及模擬酬載組成,以UHF頻段作為主要通訊頻段。因應系統所需規格與設計需求,本研究將設計自動封包解包資料的無線模組作為地面站及模擬酬載,另外設計轉發和酬載雙通道的模組作為轉發站。
    最後進行系統的架成,測試模組的通訊性能,與驗證無線網路的功能,並了解環境例如風速,地形等對於轉發網路的影響,並討論其中缺陷和可改進方式。
    ;In order to search goal in a large area, the study investigated and compared different radio communication systems to summarize the system design requirements. With knowing the theory of radio, we could plan the concept of system.
    The system consists of three parts, the ground station, the radio relay station, and the simulated payload. The UHF band is the main communications band in the communication system. The modules of ground station and simulated payload system is transceiver which could receive and transmit message. The transponder would be modules of the radio relay station.
    Because we wanted to find out shortage and improve the system, we tested the communications capabilities of modules and the abilities of the RF network.
