Abstract
The aim of this paper is the assessment of the performance of U-TDOA Position Location (PL) method on a UMTS cellular system in Mosul city, Iraq. The study area is a (3×3 km) which covers the University of Mosul campus. Simulation is used to study and evaluate the performance of U-TDOA PL method in urban area and on a highway inside the city. The effect of terrain, multipath, signal to noise ratio (SNR), Geometric Dilution Of Precision (GDOP), shadowing and the configuration of base stations on the positioning accuracy are investigated. The study is conducted on a real coordinates with the distribution of UMTS BSs as the same existing 2.5 Generation Enhanced Data rates for GSM Evolution (EDGE)Asiacell operator.
Keywords: U-TDOA, Position Location, UMTS.
