Analysis of Positioning Error for Two-Dimensional Location System

الملخص EN

This paper investigates the positioning error using different positioning techniques for two-dimensional location system.

Based on the measurement models of TOA with/without the time synchronization and TDOA techniques, the performance comparison analysis between TOA with/without the time synchronization and TDOA is presented respectively.

The performance of TOA with the time synchronization and TDOA is influenced by the specific distribution of the reference nodes.

Hence, it is hard to determine which one is better.

The performance of TDOA is always superior to TOA without the time synchronization using the same reference nodes.

These conclusions are finally illustrated by the simulation results presented in two scenarios.
