| Summary: | 碩士 === 國立高雄應用科技大學 === 電子工程系 === 99 === GPS positioning in Taiwan is not easy because of the topography and urban density issues. Using GPS positioning and digital maps, it always takes lots of time to locate the position. If the traffic information could be transmitted to other vehicles while driving, the application of GPS could be enlarged.
In this thesis, we use add direction and speed parameter of coordinates for AIS concept which is applied to improve the accuracy of the Global Positioning System (GPS). The research send the information to the positioned target by Bluetooth, and keep calculating the target coordinate in the 2-dimension to meet the criteria. As the results, the target coordinate could be well positioned in the narrow topography by using this methodology, and diversity of coordinate information.
