← ScienceWhich effect on navigation systems results from orbiting satellites' spacetime position?
A)Gravitational time dilation accrues error✓
B)Ionospheric refraction decreases signal speed
C)Increased cosmic ray induced hardware failures
D)Atomic clock precision becomes unreliable
💡 Explanation
The satellite's altitude and relative velocity cause differences via general relativity. The mechanism is gravitational time dilation, leading atomic clocks to drift at a different rate. Therefore, synchronization corrections are necessary, rather than atmospheric effects predominating at that altitude.
