The Design And Realization Of Autonomous Navigation System (navi-star2001)

Autonomous Navigation System is a important part of ITS, it can help to get safe, and smooth drive, and can ease or avoid unwanted traffic jam, and also can make the movement and usage of vehicle more convenient. It can facilitate the vehicle consumption and the environment inprovement.This paper, reviews the development history of Autonomous Navigation System-NaviStar 2001, and illustrated that it has great importance to the modernization of traffic of our country to research and develop self-designed navigation system. At the same time, this paper give the prototype of Navigation System Navi-star2001 as a example and discusses specially several aspest of the research and development: 1 .The structure design and module function assignmeng of the system; 2. The realiztion method of the module MapDisplay, RouteCalculate and RouteGuide;3.The design of properly structured data storage structure which can reflect the complex road network in reality;4. The design of VehiclePosition module, which contains road-blocked-index tech., the reception and processing of GPS data and the 3-step road match algorithm.At last, the paper make a summarizaion to the development of Navi-star2001, and make some idiographic advices to the future work on Navigation Systems.
