Abstract
A method for determining location of an observer device is disclosed. The method includes receiving basestation distance data for the observer device and applying a location algorithm to the basestation distance data to determine a computed location of the observer device. The method further includes determining whether the basestation distance data correlates to any of a plurality of observer device conditions. Upon determining the basestation data correlates with one of the observer device conditions, a location bias associated with that observer device condition is employed to correct the computed location of the observer device and produce a corrected location.
