基于TDOA算法的差分UWB室内定位系统研究
Research on differential UWB indoor positioning system based on TDOA algorithm
摘要
Abstract
When ultra-wideband(UWB)positioning technology is affected by electromagnetic interference,NLOS and oth-er conditions,the positioning environment becomes complicated,which results in low actual positioning accuracy and poor posi-tioning stability. On the basis of the TDOA-UWB indoor positioning technology,a differential UWB positioning algorithm is pro-posed by drawing on the experience of differential GPS(DGPS)technology. Combined with the weight moving average method, a differential UWB indoor positioning system based on TDOA algorithm is studied and proposed. With the Hainan EVK 2.0 sys-tem as the experimental platform,relational testing experiments were carried out. The experimental results show that the differen-tial UWB indoor positioning system based on TDOA algorithm can effectively improve the positioning accuracy and positioning stability,and the positioning errors are wholly reduced by 23% in the case of external interference.关键词
