Research on TOA positioning method considering the influence of clock error
摘要
Abstract
In order to solve the problem that clock error has a great influence on the traditional TOA positioning accuracy,this paper proposes a TOA positioning method that takes into account the influence of clock error.Firstly,the clock synchronization error is added to the TOA positioning equation as an unknown parameter.Then,the Taylor series expansion of the equation is carried out to solve the prob-lem of nonlinearization of the equation after adding unknown parameters.Finally,the least squares method is used to estimate the optimal solution of the coordinate parameters and the clock synchronization error parameters.After simulation analysis,the experimental results show that the proposed method can well weaken the influence of clock error on TOA positioning and improve the accuracy of TOA posi-tioning.关键词
