← ScienceWhich effect on signal timing is experienced in GPS satellites when gravitational potential decreases?
A)Time dilation, clocks appear slower✓
B)Length contraction affects wavelengths
C)Increased Doppler induced frequency
D)Decreased signal modulation complexity
💡 Explanation
Gravitational time dilation increases because the satellite experiences less gravitational potential; per Einstein's equivalence principle, the onboard clocks appear to tick slower relative to Earth-based observers, therefore, GPS corrections are necessary rather than clocks appearing faster or signals changing form.
