← ScienceWhich outcome results because gravitational time dilation affects GPS satellites?
A)Positional accuracy is significantly degraded✓
B)Satellite orbital decay accelerates rapidly
C)Signal encryption keys become corrupted
D)Atomic clock synchronization drifts randomly
💡 Explanation
Because of the equivalence principle, the weaker gravitational field at GPS satellite altitude causes their onboard clocks to run faster; relativistic effects mean positional accuracy degrades unless corrected. Therefore, calculations compensate, rather than causing orbital decay or key errors.
