USE OF GLOBAL POSITIONING SYSTEM IN LOCATING A RADIO TRANSMITTER

In locating the position of a radio transmitter in a radio communication network, signal timing measurements of a radio signal transmitted by the radio transmitter are obtained using respective satellite-based clocks. Clock discrepancy information about timing discrepancies between the satellite-based clocks is also obtained. The signal timing measurements are compared to obtain signal timing difference information, and the clock discrepancy information is used to eliminate effects of the timing discrepancies from the signal timing difference information.
