WebMay 6, 2024 · First of all, the GPS is system is not ideal. The statement that all satellite clocks have the same error of 38 μs/day because of relativity is actually incorrect. The Earth is not a perfect sphere, and satellite orbits are not perfectly circular. Theory of Relativity introduces several effects that need to be taken into account when dealing with precise time measurements. First, 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). Gene…

Why does GPS depend on relativity? - Physics Stack Exchange

WebSpecial and general relativity predicted that the clocks on GPS satellites, as observed by those on Earth, run 38 microseconds faster per day than those on the Earth. The design of GPS corrects for this difference; because without doing so, GPS calculated positions would accumulate errors of up to 10 kilometers per day (6 mi/d). WebEinstein's special theory of relativity includes many non-intuitive and apparently paradoxical conclusions about space and time. One of these is time dilation, the fact that a clock moving relative to an observer runs slower than an identical clock at rest in the observer's reference frame. This is clearly exhibited in the extended mean lifetime of elementary particles … booger chart
