Does the Earth's spin impact time dilation for satellites and GPS receivers?

Click For Summary
SUMMARY

The discussion centers on the impact of the Earth's spin on time dilation calculations for satellites and GPS receivers. A participant calculated the time dilation difference for a receiver on the equator and a satellite moving in orbit, finding a difference of 9.3 *10^-6, compared to 7.3 *10^-6 without considering relative velocity. This indicates that accounting for the Earth's rotational speed is significant in precise time dilation calculations. The inquiry seeks validation on the methodology and its applicability in practical scenarios.

Is it plausable to take into account the speed of the Earth's spin when calculating tmie dilation for satellites and GPS receivers?

You could take into account the satellites spining against the Earth's orbit, with the Earth's orbit and at an angle?

I put it into my project but is it a good idea or am I missing something to do this? I found that for a recevier on the equator and a satellite goin with the orbit the difference to be
9.3 *10^-6 (without relative velocity the answer is 7.3 *10^-6)

can anyone tell me if what I am doing holds for anything?
