The system bines Global Positioning System (GPS), General Packet Radio Service (GPRS), geographic information system (GIS) technology, can achieve allweather satellite positioning, digital map display, vehicle navigation and vehicle realtime monitoring. Paper introduces the research background and research and development at home and abroad, and embedded GPS and geographic information system to make an overview of related technologies. This paper analyzes the characteristics and positioning GPS satellite signal theory, describes the architecture and design of embedded GIS principles. Then give the overall system design, detailed description of a vehiclemounted terminal design, including the GPS module, voice module, the video evidence and auxiliary reversing module, wireless interface module and the preparation of procedures and so on. Article focused on the Linux USB camera under the principles of image acquisition and camera video capture procedures for the preparation and implementation of image pression to make a brief analysis. Finally, the paper gives the vehicle monitoring system expansion program. In short, this paper GPS global satellite positioning technology, GIS geographic information processing technology, CDMA data munication technology and other hightech embedded systems embedded systems applications in the vehicle monitoring system has been studied, the initial realization with allweather location, the video image acquisition and wireless transmission capabilities of the GPS vehicle monitoring system, with some research value and practical value.
