1. A method for determining a geo-location of a target station using a plurality of round-trip times (RTTs) of signals transmitted by a measuring station to the target station, and response signals received from the target station corresponding to the transmitted signals, the plurality of RTTs being placed into a plurality of bins, each bin having a count of RTTs placed in the bin, the method comprising:
selecting a bin with a highest count of RTTs (maxCb) and another bin with a next highest count of RTTs (nextCb);
determining a maximum count ratio as maxCb/nextCb;
setting the bin with maxCb to a maximum bin value based at least on a predetermined threshold of the maximum count ratio; and
selecting the RTTs that are placed in the bin that is set to the maximum bin value to determine the geo-location of the target station.
