Which consequence affects GPS satellite clock timing because of orbital velocity?

A)Time dilation reduces observed frequency
B)Clocks run faster due to gravity
C)Signal wavelength increases in transit
D)Orbital decay affects signal precision

💡 Explanation

Time dilation affects satellites due to their orbital velocity; relative to ground observers, their clocks tick slower, a consequence of spacetime. Therefore, observed frequency is less, rather than faster, because gravity's effect is partly offset.
