【 研究背景 】
海洋佔地球總表面積70%以上，是人類賴以生存的重要資源，隨著科技發展越來越進步，國際海洋運輸成為陸與陸之間重要的物流配送樞紐，於是海域環境管理成為國際上重視的議題。AIS係結合「全球定位系統」（GPS）與「無線電特高頻」（VHF）之通信技術，在海事 VHF頻段連續並自動發射本船靜態、動態、航行訊息及安全訊息，同時也自動接收周圍船舶發出的訊息，透過與其他船舶和岸台進行訊息交換以建立避碰、引航調度和海上交通管理系統。
【 研究目的 】
為監測國際海域船隻、維護航海安全、增加航行便利性及海洋環境資源保護，透過即時且準確的船舶動態資料與周遭環境監測機制，以求達到保護海洋和生態資源為目的，並利用立方衛星技術覆蓋範圍廣、訊息傳遞時間短、實用性及可靠性高、緊急應變能力及靈活性強、建置及發射成本低的優勢，以低軌道的立方衛星酬載AIS的方式，對連續、自動發射的AIS信號進行接收和傳輸，以實現遠距離、大範圍的海域航安監控網路及海洋水文資料蒐集之遙測效能。
【 執行成果 】
本計畫運用Systems Tool Kit (STK)軟體進行無人飛機酬載船舶自動識別系統(AIS)之臨空覆地範圍分析，透過無人飛機酬載AIS的方式，結合海洋地理資訊系統（Marine Geographic Information System，MGIS）強大的運算與分析能力，監測船舶的AIS動態和靜態數據，除可解決無線電波盲區的問題，亦可協助相關單位快速掌握海難事故現場及港區環境狀況提供立即應變，增進海難搜查救助及港區環境監視作業之品質及效率。並建立立方衛星酬載AIS臨空的覆蓋範圍與軌道時空運算的AGI模擬機制，以期找出最佳通訊衛星軌道及計算出地面接收站與衛星的最長通訊時間。
另一方面，本計畫以PC104模組化方式建立AIS立方衛星飛行板，接收並儲存數據資料，運行至地面站可接收範圍後，則透過TT&C進行傳送資料。
本計畫以產學合力自製臺灣的立方衛星零組件及衛星AIS本體設計製造與衛星運行模擬，可使臺灣在立方衛星的研究從學術研討進而推廣此生態鏈之民間企業，提升與推動臺灣在航太產業的進步與發展。
【 Research Background 】
The ocean accounts for more than 70% of the total surface area of the earth, and is an important resource for human survival. With the development of science and technology, international ocean transportation has become an important logistics distribution hub between land and land, so sea area environmental management has become an important international priority. topic. AIS is a combination of "Global Positioning System" (GPS) and "Radio Ultra High Frequency" (VHF) communication technology. It continuously and automatically transmits the ship's static, dynamic, navigation information and safety information in the maritime VHF frequency band, and also automatically receives surrounding ships. The information sent out is used to establish collision avoidance, pilotage dispatch and marine traffic management systems through information exchange with other ships and shore stations.
【 Research purposes 】
In order to monitor ships in international waters, maintain navigation safety, increase navigation convenience and protect marine environmental resources, through real-time and accurate ship dynamic data and surrounding environment monitoring mechanism, in order to achieve the purpose of protecting marine and ecological resources, and use cube satellite technology With the advantages of wide coverage, short message transmission time, high practicability and reliability, strong emergency response capability and flexibility, and low construction and launch costs, the continuous and automatic launch of The AIS signal is received and transmitted to realize the long-distance and large-scale sea area aviation safety monitoring network and the telemetry performance of marine hydrological data collection.
【 Implementation results 】
This project uses the Systems Tool Kit (STK) software to analyze the range of air coverage of the automatic identification system (AIS) of unmanned aircraft payloads. Through the method of unmanned aircraft payload AIS, combined with the powerful calculation of marine geographic information system (MGIS) And analysis capabilities, monitoring the AIS dynamic and static data of ships, in addition to solving the problem of radio wave blind spots, can also assist relevant units to quickly grasp the scene of maritime accidents and the environmental conditions of the port area, provide immediate response, and enhance search and rescue of shipwrecks and environmental monitoring of the port area Quality and efficiency of work. And establish the AGI simulation mechanism of the coverage area of the cubic satellite payload AIS and the orbit space-time calculation, in order to find the best communication satellite orbit and calculate the longest communication time between the ground receiving station and the satellite.
On the other hand, this plan uses PC104 modularization to build an AIS cubesat flight board to receive and store data, and after operating to the receiving range of the ground station, the data will be transmitted through TT&C.
This project uses industry-university cooperation to self-produce Taiwan's cube satellite components and satellite AIS body design and manufacture and satellite operation simulation, which will enable Taiwan's research on cube satellites to expand from academic discussions to non-governmental enterprises in this ecological chain, and enhance and promote Taiwan in the industry. Progress and development of aerospace industry.
