1. A method for geo-locating a wireless transmitter emitting a signal comprising;

  • receiving the signal at a predetermined number of sensors, said predetermined number of sensors being greater than the minimum number of sensors required to obtain the geo-location estimate, and signals from the sensors containing information used to estimate the location contain a bias error;

    determining a geo-location estimate of the wireless transmitter based on information from the predetermined number of sensors; and

    updating the geo-location estimate by recursive analysis of the bias error to thereby refine the geo-location estimate.
