%X Inaccuracy of satellite velocity in ephemeris limits the locating accuracy of satellite interference in TDOA/FDOA system, especially the locating error seriously increases with fewer reference stations. A method using TDOA realized high accuracy interference location with single reference station was proposed. TDOA locating principle of satellite interference was studied, locating mathematical models was established, trust-region method was proposed to approach the interference location, the locating method experiment was verified and then the location error was analyzed. The locating experiments using actual satellites signals verified that the method effectively improved the accuracy of satellite interference location in single reference station situation.
