各種手持裝置在日常生活的使用越來越普及，像PDA和行動電話﹔其中最為流行的即為行動電話，尤其是在1996年後電信自由化的趨勢下，行動電話的數目激增，連帶使通信網路的建設越來越完善，在GSM (Global System of Mobile communication) 的通信網路下，不但可以提供語音通信服務，更可以連結數據傳訊﹔而在2001年後，GPRS (General Packet Radio Service)服務為一種新的無線連接網路技術，一般通稱為2.5G， 運用此技術可提供更快的頻寬，與網路連結。
本論文以GPRS之網路架構為基礎，整合GPS (Global Positioning System)及相關航電與電腦設備，設計並實現一個以輕型航空器為子機的遠端監測系統。本系統設計一個航電組合系統，提供飛行於有力的協助。擷取直昇機的數位化數據與GPS數據，如位置、速度、高度等資訊，配合其他航電數據，將飛行訊息即時顯視在座艙的液晶螢幕；而導航數據則可能與電子地圖結合，提供更加的導引。本系統透過GPRS網路，將資料傳回到地面監視中心，以達到飛行監控的目的。在地面監視中心方面，接收各個子機端的資訊，經處理後儲存在資料庫伺服器，可供後續的查詢使用，進而實現 “黑盒子在地面” (Black-box on the ground)的理想。
本文展現本構想與設計的細節，並且規劃了詳細的實驗步驟來對GPRS行動通訊進行測試，驗證GPRS網路之性能，如何達成規劃的指標，藉此評估本研究構想的合理性與可靠性。

On the modern world, the handy devices are convenient in livelihood applications, such as PDA, cell phone, and etc. The most popular mobile phone has received remarkable increase in Taiwan since 1996. The network facility has completely installed and become mature in wider expansions. The mobile communication not only can provide voice communication, but also offer data link services. In 2001, when GPRS (General Packet Radio Service) has been announced as a new communication technology to connect into web network, commonly known as 2.5G, can provide much higher data rate and less fare to Internet services.
In this thesis, GPRS network-based system architecture is proposed to integrate GPS (Global Positioning System) receiver with several other avionics devices to design and implement dynamic data surveillance for helicopters. In this design, the airborne digitalized data and GPS data of position, speed, altitude, are combined with other avionics data, while the ND may display GIS map for flight director. The client system also sends these data through GPRS network to the surveillance center as the server system. The server system collects and analyzes the data from several client systems, and processes and stores those real time data into the database server for querying to realize an ideal of “Black Box on the ground”.
This paper demonstrates the concept and design of this proposed system in details, carries out several experiments to test the performance of GPRS mobile network, and verifies the feasibility and reliability of the proposed system.
