中文摘要 | GPS(Global Positioning System)係以接收美國國防部GPS通訊衛星所發射之P (Precision)或C/A(Coarse/Acquision)碼得到量測點之座標,由於大氣層中電離層及對流 層效應,會引起測量誤差,因此目前皆以DGPS差分定位法來修正量測誤差,提昇精確度. 本研究計劃著重GPS接收控制器之設計,由GPS感測器所接收到之位置座標傳送至控制器, 經收集、處理及計算後顯示其座標值,利用單晶片微電腦外加記憶體和輸出/入元件組成此 控制電路.在個人電腦上建立數位地圖之資料庫,即為地理資訊系統(GIS),結合兩系統 成為自動定位系統,此整合系統在自動導航上有其實用性. |
英文摘要 | The Global Positioning Systems (GPS) was developed to receiving and decoding of P (Precision) or C/A (Coarse/Acquision) code transmitted from the GPS satellites of the Department of Defense, USA, and obtain the local coordinate of positioning point. However, exist a ionospheric and tropospheric delay effect will induce some undesirable common error during the process of receiving GPS coordinate. Therefor, the differential GPS was often adopted to modify the measurement error and to improve accuracies. In this study, implies the design of the GPS receiver's controller, base on the reception of positioning coordinate from GPS sensor board to transmit on the controller. Through acquire, process and calculate to produce and display it's coordinate. We are using some RAM, ROM, I/O chip and peripheral devices expend into single chip microprocessor to consist of a control system that perform the above operation. An Geographic Information System (GIS) which establish a database information of the digital map system at the personal computer. The integration both system is a automatic positioning system, and the system is realized and applied for automatic navigation. |
