Indeed. So we have two co-axial counter-rotating merry go rounds with clocks on their rims. I think the only real difference this makes to my answer is that the maths of working out what each clock actually sees from a counter-rotating clock is merely annoying, not actively difficult.Nugatory said:This simpler setup still captures what I think is the essence of @name123's problem: How can it be that all the satellites log the same arrival time for the flashes, and their clocks match when they meet every half-orbit, even though the clocks on the satellites are mutually time-dilated so that the satellite observers will always find all the other satellite clocks to running slow for the entire orbit?
In particular, chaining together local Einstein frames still fails, and for the same reason. Global inertial frames are available, but any chosen clock is only instantaneously at rest, or never at rest, in any chosen one.
