Patent ID: 11778581

Abstract:
A method in a wireless device (WD) for determining a best-fit geo-location of a target station is described. The best-fit geo-location is determined using a plurality of round-trip times (RTTs). The target station is movable. The method includes assigning values to current target station parameters. The current target station parameters include a current location for the target station and movement parameters. A plurality of square residuals is determined based at least in part on the current target station parameters. Each square residual of the plurality of square residuals corresponds to one RTT. A minimum of a sum of squared residuals (SSR) is determined based at least on the plurality of square residuals. best-fit parameters are determined based at least in part on the determined minimum of the SSR. In addition, the best-fit geo-location of the target station is determined based at least on the best-fit parameters.
