Abstract
The main function of geographic information system (GIS) is to collect, store, manage, retrieve, process and analyze geospatial data. The function of GIS depends on the acquisition of location information, and the integrated navigation technology can provide more accurate navigation and positioning information. In this paper, combined with GIS positioning and fluorescent chemical sensor, the debugging software of upper computer is designed and implemented. The positioning information of the navigation panel is transmitted to the computer through the serial port. Further analysis and research will help to provide feedback on the navigation controller and improve the design. After the design is completed, the integrated navigation system will be put into application. Based on the research of GPS navigation technology, map matching technology and traffic flow, this paper explores the navigation system which can meet the traffic characteristics from the technical point of view.
