I know Cutty replied below also. I wanted to point out that in your list of hardware, the GPS module you mentioned doesn't fit the most basic requirements. It doesn't bring out the 1PPS pulse. The system isn't critically dependent on GPS provided position. They could even make that user definable. Timing is critical. The receiver must know the current time down into the low nanoseconds.
That's used to define when the signals are received. As mentioned previously, there's custom hardware used to condition those signals prior to being applied to the ADC in the chosen microcontroller.
