What does that have to do with Doppler shift? If the GPS transmitters are ground based, then there should be no relative motion between the transmitter and receiver, therefor no Doppler shift.
It would seem you don't understand how the Doppler effect works. How surprising.
Oh? This should be interesting.
Any electromagnetic waves are going to be emitted at a certain velocity...
Yes, that velocity would be the speed of light (also known as c).
...which will of course be affected by the current velocity of the Earth.
Umm... No. The speed of light is a constant, regardless of your frame of reference.
However, the moment the waves leave the transmitter they are no longer affected by Universal Acceleration. As such, there will be relative motion between the transmitted waves and the receiver beyond the initial relative velocity, which will, of course, lead to the Doppler effect being observable.
Ummm... No, again. The Doppler effect refers to the change in frequency of a signal, not in its velocity.
Your failing lies in the misunderstanding of the cause of the Doppler effect. You seem to think that it's strictly linked to relative motion between the transmitter and the receiver. It's not.
I think that you're the one who has demonstrated a misunderstanding of the Doppler effect.
In the case of the train whistle - The train whistle is the transmitter and the receiver is the listener at the crossing and the relative motion is the motion of the train. The change in frequency is the change in frequency heard by the listener at the crossing.
In the case of the Doppler Effect on the amateur radio "Moon Bounce" the transmitter is the transmission to the moon by the amateur radio operator and the receiver is the reception on the amateur radio operator's receiver on the earth and the relative motion is the movement of the moon. The change in frequency is heard on the receiver by the tone of the voice or the tone sent.This is particular noticeable on single side band transmission and reception.
Ask Tom Bishop:The question (which has not been answered as yet) :
What is your answer to the question of how the amateur radio operators measured the distance from the earth to the moon by transmitting a signal to the moon, and noting the time required for it to return on their receiver and multiplying the "one way time" by
the speed of radio waves to get the distance from the earth to the moon ?
What is your opinion of radar ?
This is basically the same as the amateur radio operations. The radar sends a pulse. Then the radar receives any echos from the target. The radar then converts the time for the target signal to return and also computes the distance by using
the speed of radio waves.
