Abstract
A method for enhanced location determination using temporal, spatial and/or frequency diversity. Multiple ranging signal measurements are obtained from each signal source using either temporal, spatial and/or frequency diversity. In one embodiment, the multiple ranging signal measurements are combined using a metric to obtain a single ranging signal measurement. The location determination solution is then calculated using the single ranging signal measurement. In a second embodiment, a location determination solution is calculated for each of the multiple ranging signal measurements to result in multiple location determination solutions. A metric is then used to combine the multiple location determination solutions to result in a single location determination solution.
