← ScienceWithin GPS satellites orbiting Earth, which mechanism causes oscillator frequency error?
A)Relativistic Doppler shifting accumulates✓
B)Gravitational time dilation reduces
C)Tropospheric refraction indexes diverge
D)Solar wind induction interferes
💡 Explanation
Differential aging occurs because special relativity's time dilation produces faster clock rates due to the satellite’s motion relative to Earth's surface-based observers; therefore, frequency error accumulates through Doppler shifts, rather than altered frame rates. A stronger gravitational gradient implies more space-time curvature.
