Locking it up to a 10 MHz seems doable, you need to use the fractional
division, but you can make it spot on if my back-of-the-envelope
analysis is correct.
You will have to implement the GPS receiver. You could do SDR, but I
would toss a FPGA in for the digital correlator frontend stuff and then
let the CPU do the rest.
It's a good pair of chips to create some fun. :)
It will give you L1, but not L2 or L5.
Cheers,
Magnus
