5. Conclusion The commenter is correct that directly measuring the L1

precision of ±0.025 Hz is unrealistic for a GPS receiver.

three or four steps in the math of trilateration, the EXACT POSITION of

operation with only one carrier: L1).

completely nonsense, you contradict yourself. It's fourangulation, not
triangulation. And you can detect four frequency signals out of a single
signal, something called FFT etc. Here an example, 20 and 21 Hz signal
