A typical direct sampling receiver would sample the RF at 16.368, and 
that puts the L1 received signal nicely at fs/4.  The P code would 
overlap the sampling bandwidth of 8.184 MHz, but the C/A code fits well 
within that range. And, since it's not at "zero", any doppler just moves 
it from the center, but it's still "positive" frequency.
