← ScienceWhich distortion occurs regarding navigation due to differences in gravitational potential affecting spacetime?
A)Cumulative GPS signal phase shifts✓
B)Satellite orbital decay accelerates rapidly
C)Increased atmospheric drag coefficients occur
D)Ionospheric radio frequency noise increases
💡 Explanation
Cumulative GPS signal phase shifts happen because gravitational potential differences cause spacetime curvature affecting the rate at which clocks tick (gravitational time dilation), therefore GPS needs relativistic corrections, rather than just orbital calculations/atmospheric effects.
