Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that general relativity is needed for GPS satellite accuracy?

Yes. A physics Q&A and a NASA page both state that GPS requires general-relativistic clock corrections, otherwise timing errors accumulate and positions become inaccurate. A review paper and a study also note relativity must be accounted for in GPS timing.
