Abstract:
The correction for the gravitational time dilation and the speed of movement is introduced into the on-board clocks of the GPS satellites, since it is believed that in the orbit of 20 184 km, the clock without correction runs 38 microseconds per day faster than on Earth In this work, the need for clock correction is explained on the basis of purely classical concepts without using the statements of the theory of relativity about time dilation and the constancy of the speed of light. It is shown that, in fact, the speed of electromagnetic radiation does not remain constant in the gravitational field but changes, and the signal from a satellite to a receiver on Earth comes faster than from a source on Earth to a satellite. Time in orbit does not change and clocks run at the same speed as clocks on Earth. The receiver on Earth sees an increased signal frequency not because of the acceleration of the satellite's atomic clock, but because of the increase in the speed of the photons and the resulting Doppler effect.
