Application of Chan Location Algorithm in 3-Dimensional Space Location

Qin Feng

Open publisher page 4 citations

Abstract

Wireless location algorithm based on TOA/TDOA has been researched and compared,and precise ranging technology based on TOA has been analyzed in this paper.In view of that the existing location algorithm is always in 2-dimensional form,Chan algorithm has been concluded in 3-dimensional form and a 3-dimensional location method based on TOA is proposed.The method transforms the nonlinear location equation into linear form by using initialization estimation coming from two-step weighed least square,then calculates the location estimation.The method is simple and precise.The simulation shows its theoretic value.
