[time-nuts] GPS down converter question

For GPS C/A with wide correlator, about 2 MHz; if you want Galileo BOC and
(eventually) GPS L1C, or legacy C/A with narrow correlator, about 8 MHz;
for GPS P code about 20 MHz.  Books on GNSS software receivers will detail
the many tradeoffs available---if you're starting out with a
proof-of-concept lab receiver, go for 8 MHz.
