GPS satellites carry atomic clocks, and relativity makes them tick at a different rate from clocks on Earth. Motion slows them while weaker gravity speeds them up; the net difference is about 38 microseconds a day. GPS uses radio-signal timing to locate receivers, so engineers include relativity corrections.
