Claim 10:
11. A method comprising:
obtaining, from a plurality of sensors, measurements of first magnetic fields generated by a portion of a plurality of antennae;
evaluating predetermined functions using the first magnetic field measurements to obtain first position and orientation information for the plurality of sensors;
obtaining second magnetic field measurements from the plurality of sensors for the plurality of antennae; and
searching, starting with the first position information, a simulated map for second position information of the plurality of sensors such that the difference between (a) the sum of simulated magnetic field corresponding to the second position information and the interference magnetic field, the sum being rotated according to orientation information, and (b) the second magnetic field measurements is minimized.
