    That is the satellites' clocks are slower than Earth's clocks by 7214 nanoseconds a day due to their velocity. Note that this speed of 3874 m/s is measured relative to Earth's center rather than its surface where the GPS receivers (and users) are. This is because Earth's equipotential makes net time dilation equal across its geodesic surface. [18]
