Which limitation on the GPS system occurs as signal errors increase due to navigation satellites experiencing changes within gravitational fields?

A)Clock drift becomes more accentuated
B)Hardware faults propagate more quickly
C)Computational strain intensifies noticeably
D)Signal absorption through higher layers

💡 Explanation

The GPS accuracy degrades because general relativity predicts gravitational fields affect time; therefore, the **gravitational time dilation** accumulates errors between satellite and receiver clocks, rather than other sources of system processing faults because the satellite's altitude relative to the Earth matters.
