Claim One:
1. A method for resolving ambiguity in location determination with a number, N, of ambiguous location determination solutions using clock temporal bias value comprising: generating a probability distribution function (PDF) model for clock temporal bias; obtaining N clock temporal bias values of a clock within a mobile station receiver for the N ambiguous location determination solutions, wherein at least one of the N ambiguous location determination solutions is an ambiguous solution due to presence of noisy measurements; inserting each of the N clock temporal bias values into the PDF model; evaluating the PDF model to get N PDF values; setting N goodness metrics to the N PDF values; comparing the N goodness metrics; defining a maximum goodness metric as the largest of the N goodness metrics; and determining a final location determination solution by selecting a one of the N ambiguous location determination solutions having the maximum goodness metric.
