Abstract
A method for combining a plurality of individual location measurements, for use in a wireless location system, includes the following steps. A quality metric for a single location estimate is computed along with individual quality metrics and individual weightings for each individual location measurement. In addition, weighting operations incorporating a quality metric for a single location are performed, and the measurement weights are adjusted based on information about co-location groups; and a decision metric and common bias accounting for multiple reference measurements are computed.
