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.
