I found this homebrew GPS receiver project recently:

No custom specialized chips that are unavailable in small quantities, or which
will go obsolete in a few months. I think the best solution for the open
source GPS community is to design open source receivers with commodity parts
that won't be discontinued in the near future, or for which another commodity
part can be substituted if need be. Maybe somebody can extend this design with
a 2-bit ADC on the end (not me, too many projects here already...)

I still think that finding appropriate off the shelf parts to make a
subharmonic sampler would be a better strategy..
It's all about whether you want IF filters and a mixer+LO or RF filters.
I think the amps are the same either way.
