Which consequence occurs in GPS satellites because altitude changes spacetime?

A)Clock drift relative to Earth
B)Signal interference from solar flares
C)Increased atmospheric drag on panels
D)Reduced gravitational attraction towards Earth

💡 Explanation

Differential time dilation, via general relativity, is the mechanism affecting satellite clocks. Increased altitude causes time to pass more quickly relative to Earth, because the spacetime curvature is reduced; therefore clock drift occurs, rather than the other atmospheric or gravitational disturbances.
