Abstract
A method for determining a geo-location of a target station. The method includes transmitting a plurality of ranging packets to a target station and receiving a plurality of response packets transmitted by the target station in response. A plurality of round-trip times (RTTs) are determined based on the ranging packets and the response packets. A plurality of angles of arrival (AOAs) are determined based on the response packets. First and second pluralities of squared residuals are calculated for the plurality of RTTs and the plurality of AOAs, respectively. A third plurality of squared residuals is generated by summing the first and second pluralities. A minimum of a sum of the third plurality is calculated to identify best-fit location parameters for the target station. A circular error probability (CEP) ellipse is generated using the best-fit location parameters and a geo-location of the target station is determined based on the CEP ellipse.
