← ScienceWhich risk increases when a GPS satellite's clock malfunctions, impacting perceived location?
A)Ephemeris data becomes inaccurate✓
B)Relativistic effects reverse direction
C)Doppler shift calculations are neutralized
D)Atomic clock cesium degrades rapidly
💡 Explanation
Inaccurate time impacts ephemeris, because the satellite's position data becomes unreliable due to the error from spacetime distortion; therefore, range calculations are off, rather than relativistic, Doppler, or atomic breakdowns directly causing position inaccuracies.
