← ScienceWhich increasing risk results within a GPS satellite's atomic clock when its orbital velocity constraint decreases?
A)Positional drift due to computation errors✓
B)Increased signal interference from Earth
C)Thermal runaway damaging frequency stability
D)Crystal oscillator aging acceleration effect
💡 Explanation
Lower orbital velocity reduces the time dilation effect predicted by general relativity; because the satellite's clock appears to tick faster relative to ground-based clocks, its onboard calculations need correction for spacetime, therefore positional error accumulates, rather than other clock-specific failure modes.
