Dilution of precision for time difference of arrival with station deployment

A study is conducted with the aim to reveal relationship between performance of moving object tracking algorithms and anchor (station) deployment. The dilution precision (DoP) for time difference arrival (TDoA) technique respect deployment studied. Linear non-linear estimators are used TDoA algorithms. research findings linear estimator indicate that DoP attains a lower value when other anchors scattered around central anchor; estimator, optimal target tag. Experiments on both location related in practical situations objects integrated Kalman filter an ultra-wideband (UWB)-based real-time localization system. work provides guideline deploying UWB-based systems.
