Time Sorting Method for TOA-Based 3D Hyperbolic Positioning System

Abstract

Positioning technology is now very important and has many advantages. One way to determine the position is to use a hyperbolic algorithm. The algorithm can use the time-of-arrival (TOA) parameter of the target signal to determine the position of the target in three dimensions. In this paper, we examine target positioning using existing hyperbolic positioning systems. In some cases, an error was detected when the x-, y-, and z-coordinates were imaginary. A time sorting method was added to solve this problem. Performance improvements were then made using this method. This method improves target positioning accuracy and avoids errors.
