Abstract

In a wireless location system configured to use a baseline correlation method, an iterative approach to increasing location accuracy is disclosed. The quality of received signals is ordered from highest to lowest and used to calculate an initial location. The initial location is modified using the lower quality signals as constrained by the time and frequency deviation from the initial location and velocity estimate.
