1. A method for locating a standard, mobile-communications, radio transmitter in a cellularized communications system, comprising:

  • at first, second and third sensor stations, receiving a signal carrying voice/traffic-related data from the mobile radio transmitter;

    at the first sensor station, generating replicated signal data and generating a reduced form of the replicated signal data, said replicated signal data comprising voice/traffic-related signal data received at the first sensor station;

    communicating the reduced form of the replicated signal data to the second and third sensor stations;

    at the second and third sensor stations, reconstructing the replicated signal data from the reduced form of the replicated signal data, whereby voice/traffic-related signal data received at the first sensor station is recovered at the second and third sensor stations, and performing correlation processing with the voice/traffic-related signal data received at the second and third sensor stations and the replicated signal data communicated by the first sensor station to produce location-related signal parameters;

    communicating the location-related signal parameters from the second and third sensor stations to a central site; and

    estimating the position of the mobile transmitter from the location-related signal parameters.
