Beschreibung
Zusammenfassung:	A method and apparatus for processing global navigation satellite signals, or radar signals, specifies an arrival time of a signal having a shape similar to a known pseudo-random noise sequence (PRN) of rectangular pulses. Two quadrature signals are generated and six correlations are calculated and multiplied by a correlation coefficient. The results of one of quadrature signals are summed and a timing error is estimated. An improved signal arrival time is generated by adding the estimated timing error to the predicted signal arrival time is generated.
