← ScienceWhich 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.
