Why do GPS satellites tick precisely 38 microseconds faster than clocks on Earth? The GPS satellite clocks actually need to tick over 38 microseconds per day (!) slower than terrestrial clocks in order to compensate for relativistic time dilation and contraction effects – at least, they would tick that much slower if they were still …
