Consider a clock aboard a satellite orbiting the Earth, such as a Global Positioning System GPS transmitter. There are two major relativistic influences upon its rate of timekeeping a special relativistic correction for its orbital speed and a general relativistic correction for its orbital altitude. Both of these effects can be treated at an introductory level, making for an appealing application of relativity to everyday life.
