| Abstract: | 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 fea-sibility were possessed in practice engineering. |
