Abstract:	對生態環境監測的而言，由於衛星或飛機遙測技術大都適用於大範圍、長期性的監測，對於小區域、突發事件的反應通常不具機動性。一個低成本、經濟有效的無人載具遙測系統，便可彌補這些限制。對遙測應用而言，一遙測系統包括了載具的定位、感測器的設計與校正、遙測資料與地理資訊系統的整合。而整個遙測系統上各感測器所遙測的資訊及GPS數據皆需透過ㄧ傳輸系統將其訊號傳送至地面接收端。因此發展ㄧ具有整合性的傳輸系統，將不僅可減輕其無人載具負載的重量同時亦能節省無人載具負載區的體積並損耗較少的電源。本文即對一整合性的傳輸系統做ㄧ縝密的規劃與研製。 For environment and ecosystem monitoring, it is well known that both satellite-borne and airborne remote sensing are suitable for wide-area and long-term monitoring of environment. For small areas or accidental events, however, they are not mobile enough. Thus, a cost effective means, such as an unmanned vehicle remote sensing system(UVRSS), dose relief this disadvantage. A complete UVRSS at least consist of: vehicle positioning, sensor design and calibration, integration of remotely sensed data and GIS data, and a data transmission system. For real-time application and data storage limitation, the remote sensing data and acquired by an UVRSS should directly downlink to receiver on ground. Consequently, it is necessary to develop an integrated transmission system which is light weight of vehicle, space-saving and less power consumption. Hence, this paper is devoted to the system design, implementation, and testing. Experimental test shows that the transmission system well work at effective distance 80m, and solve data storage limitation.
