This paper presents an intelligent positioning algorithm for transmitting station. By using GPS and RSSI, the influence of RSSI value can be reduced. The advantages of multi angle positioning method and centroid localization method are combined. The algorithm required less precision positioning device, also the least square method is used to reduce the error of location in urban areas. The method is simple and convenient, and the simulation results show the practicability of the algorithm. Set

Simulation testing results are shown in Figures. 6, 7 and 8, it can be seen that positioning accuracy can be improved in different geographical environment. 205 is used to reduce the error of location in urban areas. The simulation results show that the improved algorithm are not affected by the dissipation factor, can improve the positioning accuracy in a variety of distance, is a universal positioning algorithm. Only a certain number of samples were collected to support the operation of precision. This algorithm is designed for portable device applications, you can put the device on the flow of vehicles in the monitoring, it is more conducive for detection and location.
