Zusammenfassung:	A method in a location enabled mobile wireless receiver having an oscillator, including determining a change in cellular network based frequency error of the oscillator ( 250 ), based on a difference ( 230 ) between a cellular network based frequency error of the oscillator and a reference cellular network based frequency error ( 210 ) of the oscillator, determining a first frequency error of the oscillator by summing ( 250 ) a reference satellite positioning system receiver based oscillator frequency error ( 220 ) with the change in cellular network based frequency error of the oscillator.
