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.

Abstract
A location estimation method is provided. The method locates coordinates of a mobile station (MS) by referencing a plurality of base stations (BS). A geometric distribution of the BS is analyzed to provide a list of conditional equations. A virtual BS is allocated, having a virtual distance to the MS to provide a constraint equation. The MS location is derived from the conditional equations and the constraint equation.
