If you go back into the papers from the early 1980's there is one where they
used a high gain antenna and no knowledge of the coding scheme to pull timing
off of GPS. I believe it was at White Sands, but that could be wrong.
One can just run it into a squaring circuit and recover the carrier, for
instance. Recovering accurate carrier frequency isn't going to help you
navigate a ICBM to a hardened target. Knowing the P-code is.
