Described herein is an object located system for locating an object (10) whi ch produces identifying signals. The system comprises a plurality of receivers sites (22, 24, 26, 28) arranged in an array (20) for receiving signals from the object (10) and for receiving a common time reference in the form signal s received from a global navigation system (50). The array (20) comprises a reference receiver site (22) and three auxiliary receiver sites (24, 26, 28) , the auxiliary sites being connected to the reference site by data links (34, 36, 38). Each receiver site (22, 24, 26, 28) receives signals (42, 44, 46, 4 8) from the object (10) and timing control signals (52, 54, 56, 58) from a glob al navigation system (50). Each site determines a time difference between the receipt of the object signals and the timing signals, the auxiliary sites (2 4, 26, 28) providing data signals on data links (34, 36, 38) to the reference site (22) where the location of the object (10) is determined.
