Does anybody agree that using a Uno is possible with only a reasonable amount of effort?
I believe the only limitation is the processing power of the Uno. This is why I said it will not work with frequent updates. Can we agree on that? If not, why not?
The Speed is only relevant if you want to do it in real time.
Is there anyone who would wish to have this capability using Arduino? Can you think of any applications? Am I the only one?

I thought that timing in GPS was crucial, given that you're measuring the distances to a set of objects all moving. Given that you're trying to measure cycle-to-cycle variations in the phase if a signal that has a very short wave length, with the signal passing between objects that are moving at thousands of miles per hour, it seems to me that you have a *lot* of data to process and that the data is inherently real time.I could be wrong - I have no idea how this clever algorithm works other than what you've told us - but to me this sounds like a maths-heavy number crunching problem. This is why I thought you might want to get it working on a decent spec PC (if that's possible) and then see what resources it needs and whether you can finesse it down to run on something that's about a thousands times slower.
This stuff works I have seen it in practice and it is pretty neat for those who have the need for it. I wonder whether SA would be turned back on if there were cheaply available RTK systems. The combination of RTK and some of the emerging and established technologies is a scary mix for some people.
