← ScienceWhich navigational error accumulates aboard long-duration spacecraft because of special relativity?
A)Positional drift relative inertial frame✓
B)Faster atomic clock frequency decline
C)Incorrect Doppler shift compensation ranges
D)Reduced navigational star target accuracy
💡 Explanation
A difference arises because of time dilation; the on-board clocks tick slower relative to Earth's inertial frame. These accumulate during extended missions due to velocity time dilation according to the equivalence principle; therefore a positional drift occurs, rather than clock slowdown which would show measurement consistency.
