A method for locating a mobile transmitter comprises the steps of (a) making a first estimate of the location of the mobile transmitter on the basis of a first transmission from the mobile transmitter; (b) causing the mobile transmitter to emit a second transmission; (c) making a second estimate of the location of the mobile transmitter on the basis of the second transmission; and (d) combining at least the first and second estimates to obtain an improved, more accurate estimate of the location of the mobile transmitter. Step (b) may comprise auditing the mobile transmitter to elicit an audit response, or terminating the call (hanging up) and then initiating another call by paging the mobile transmitter to elicit a page response. Step (d) preferably comprises averaging a plurality of statistically-independent location estimates.
