The peak-to-null bandwidth of the C/A signal (on L1=1575 MHz) is about 1 MHz, and the peak-to-null bandwidth of the P/Y signal (on L1 and L2=1227 MHz) is about 10 MHz. The C/A signal is for civilian use, and can be used directly. The P/Y signal can also be used by correlating the signals on L1 and L2. This is much more complicated than using C/A, but you can get better positioning accuracy. _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
