No Observable Twin Paradox in GPS

Despite SR being touted as critical for GPS, there's no observable time
dilation between two satellites moving at the same speed in opposite
directions, as the twin paradox would suggest.
Why? Because the system averages orbital parameters, assuming symmetry.
That’s another silent way the system discards relativistic uniqueness
for practical operation.
The so-called “relativistic corrections” in GPS software mostly consist
of:
• Orbital modeling (Newtonian mechanics),
• Empirical clock bias estimation,
• Sagnac effect compensation (due to Earth’s rotation).
None of these require full GR field equations. The system works by
compensating for delays and synchronizing signals based on observed
discrepancies, not theoretical purity.
If General Relativity disappeared tomorrow, GPS would still
function—with a different set of empirical fudge factors.
According to standard lore:
• Special Relativity (SR) predicts satellite clocks tick slower due to
orbital speed (~7,000 km/h).
• General Relativity (GR) predicts clocks tick faster due to being
higher in Earth’s gravity well.
The net effect? Satellite clocks tick faster by ~38 microseconds per
day. GPS allegedly corrects for this in software.
But this claim collapses under scrutiny.
