1. A method for determining a location of a mobile receiver, the method comprising:

  • measuring a plurality of signal strengths received by a mobile receiver, wherein the plurality of signal strengths are associated with a plurality of cellular stations, wherein the plurality of signal strengths is associated with a specific point in time;

    combining the plurality of signal strengths with a plurality of signal path modeling parameters to create a propagation path loss model of the path between the plurality of cellular stations and the mobile receiver;

    applying a non-linear estimation algorithm to the propagation path loss model;

    generating a plurality of distances, wherein each distance is associated with the mobile receiver and each of the plurality of cellular stations; and

    computing the location of the mobile receiver by iterating the non-linear estimation algorithm and resulting mobile receiver position until converged.
