摘　　要：为了满足航空旅客在航站楼内位置服务的需要,提出一种集合和加权径向基函数相融合的室内定位方法。该方法能够充分利用信号弱的AP(Access Point)对定位的作用,降低旅客走动对定位的影响,弥补传统算法只采用信号强AP的不足,同时具有对AP突发故障不敏感的特点。实验表明在误差2 m内,该算法与现有的典型定位算法相比,能够大幅提高定位准确度,满足航站楼内位置服务的需要。To provide location-based service （LBS） to air travellers in airport terminals, we present an indoor positioning technology which integrates the sets with weighted radial basis function. This method can makes full use of the role of weak signal strength of APs （ access point） on positioning, reduces the impact of travellers＇ moving on loealisation, and makes up the deficiency of traditional algorithm which only uses APs with strong signals. At the same time it has the characteristic of insensitive to APs＇ unexpected broken. Experiment illustrates that the method has the error within the distance of 2 meters. Compared with existing typical localisation algorithms, it can greatly improve the accuracy of positioning, and can meet the demand of LBS in airport terminals.
