.3 G Integrated System In A Number Of Technical Research And Practice

With the widespread uses of computer technology, satellites positioning technology, GIS and mobile telecommunication technology, the 3G Integrated-System has gotten a high speed development, as an important part of Intelligent Transportation System. This Integrated-System has been studied intensively in this paper. The content of this paper mostly include following points:1. Introduce the state of development of the 3G-IS in both at home and abroad, and point out the purpose and meaning of the 3G-IS.2. Introduce the principle of satellites positioning technology, GIS and mobile telecommunication technology, and detailedly discuss the integrated technology and the application about these technologies in the 3G-IS.3. Design a Vehicle Navigation and Monitoring System base on the 3G integrate technology, as a practice for 3G-IS, it has been tested many times. The test results show that the software part and hardware part run steadily, reliably, and all technical specification meet the needs of design. If this system be consummated, it can become an applied system.In the end there is a summary of entire paper and the envisagement of future work.
