摘要
对当前的无线定位技术进行了考察,给出了一个基于GIS路网的GSM定位技术数学模型和算法,解决了基于GIS路网的一维定位问题。在此基础上,对所设计的数学模型和算法从实践上进行了可行性验证。从实践工程的角度引入了GIS道路拓扑分析及移动速度和方向参数,对模型本身做到了修正,增加了定位精度,使模型算法本身具有了稳定性。
Current technology of wireless locating was reviewed, and a mathematical model and algorithm of locating with GSM that based the road web in geographic information system （GIS） were presented. The problem of linear locating with GSM was solved. In practice, the velocity and direction parameters of migratory object that will locate its position to ameliorate the model and algorithm were introduced, and the road parameters in our model are modified. The locating precision was improved and the model and algorithm feasibility were possessed in practice engineering.
