发明名称 TIME DETERMINATION IN SATELLITE POSITIONING SYSTEM RECEIVERS AND METHODS THEREFOR
摘要 Method in a Global Positioning System (GPS) receivers, including determining pseudorange (PNR) measurements for at least four satellites ( 210 ), determining a coarse time ( 220 ) corresponding to the pseudorange measurement, determining an offset time ( 240 ) between a periodic GPS event of one of the four satellites and the coarse time, determining a time correction delta ( 250 ) based upon the period of the Periodic GPS event, the offset time and the coarse time if an error of the coarse time is less than ½ the period of the periodic GPS event, and determining corrected time ( 260 ) based upon the coarse time and the time correction delta if the error of the coarse time is less than ½ the period of the periodic GPS event.
