← ScienceWhich mechanism causes increased signal latency from GPS satellites?
A)Spacetime curvature near Earth distorts signals✓
B)Atmospheric ionization delays radio transmissions
C)Solar flares disrupt satellite communications
D)Satellite orbital eccentricity varies path length
💡 Explanation
Gravitational time dilation affects space-based clocks. Spacetime curvature near Earth causes photons to travel different path lengths. Therefore, it generates variable communication delays because clocks tick faster farther from Earth, rather than increased signal time from solar flares.
