1. A location estimation method for locating a mobile station (MS) by a plurality of base stations (BSs), comprising:

  • analyzing a geometric distribution of the BSs to provide a list of conditional equations;

    rendering a GDOP contour based on the analysis of the geometric distribution;

    allocating at least one virtual BS to a position according to the GDOP contour, said virtual BS having a virtual distance to the MS to provide a constraint equation; and

    estimating the MS location based on the conditional equations and the constraint equations.
