Which effect on GPS accuracy happens near massive objects?

A)Gravitational time dilation error
B)Increased atmospheric refraction index
C)Signal multipath interference increases
D)Atomic clock synchronization variance

💡 Explanation

Near massive objects, gravity curves spacetime, causing gravitational time dilation of satellite clocks because atomic clocks tick slower, and GPS relies on precise timing; therefore, timing errors increase rather than relying on atmosphere effects or signal interference.
