System performance evaluation of mobile positioning methods

This paper presents a simulation methodology for evaluating the performance of location techniques for cellular systems. The simulation tool developed enables quantification of the final system performance for various choices of components such as measurement techniques, channel models and position computation methods. Positioning performance of a GSM and IS-136 cellular system is shown for a specific choice of measurements and algorithms in various radio environments. The variation in performance with the choices of system parameters such as number of measurements made per position computation is shown.
