Abstract

A system for locating an object that produces identifying signals comprises a plurality of receiver sites arranged in an array for receiving signals from the object and for receiving a common time reference in the form signals received from a global navigation system. The array comprises a reference receiver site and three auxiliary receiver sites that are connected to the reference site by data links. Each receiver site receives signals from the object and timing control signals from a global navigation system. Each site determines a time difference between the receipt of the object signals and the timing signals, the auxiliary sites providing data signals on data links to the reference site where the location of the object is determined.
