Abstract
Method and apparatus for detecting 50 Hz GPS data-bit boundaries and detecting satellite-signal reception. The apparatus includes a correlating unit and a data-bit boundary detecting unit. The correlating unit outputs first (I) correlation integral values and second (Q) correlation integral values sequentially by calculating a correlation integrals between a satellite pulse train and a replica PN code. The data-bit boundary detecting unit changes the sign of each of the first (I) correlation integral values and second (Q) correlation integral values, based on comparing each of the first and second correlation integral values with an immediately previously outputted (first or second, respectively) correlation integral value, and generates data-bit boundary detection signals having information corresponding to the data-bit boundary using the changed correlation integral values. Thus, the data-bit boundary in GPS satellite signals can be detected.
