The correction is needed so that any time announced by any satellite … The theory of relativity introduces several effects that need to be taken into account when dealing with precise time measurements. According to special relativity, time passes differently for objects in relative motion. That is known as kinetic time dilation: in an inertial reference frame, the faster an object moves, the slower its time appears to pass (as measured by the frame's clocks). Gener…
