對生態環境監測而言，衛星遙測技術提供了經濟，且相當安全、可靠的，適用於大範圍、長期性變化的監控。但機動性與靈活性較差，因此對於小範圍、突發事件的監控，則須仰賴無人載具遙測做即時定點的監測，而基本的監控設備，除了影像感測器，載具的地理定位資料也是不可或缺的，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。 為了得到更精確、即時的載具全球地位資料 ( GPS )，以及擴大監測範圍，因此，加快GPS全球地理定位訊號的下載速度，達到一秒更新一次，以及加大系統的發射功率，增加無線的傳輸距離，即此研究的最大目的。 For environment and ecosystem observation, the satellite-borne remote sensing technologies provide an efficient、stable and safe way suitable for wide-area and long-time observation of environment. But the mobility and adaptability are not good enough. Thus, for small areas and accidental events, we depend on an “unmanned vehicle remote sensing system “(UVRSS) to do local and real-time monitoring. In addition of the image sensor, the information of the vehicle position is an essential demand. So developing an integrated transmission system not only can decrease the weight of vehicle, but also decreases space of UVRSS and power consumption. In order to get more precise and real-time information of the vehicle position and increase the range of monitoring, increasing the download speed of “Global positioning system “ ( GPS ) data to refresh per second and increasing the emitter power of system are the major goals of our research.
