Default Doppler effect

The Doppler effect comes into play anytime two objects are moving relative
to each other.

Ham satellites often go up on one sideband and retransmit on the opposit
sideband to help counter this effect.

You all know that the frequency from a satellite is changing.

Does anybody know if the frequency from a spacecraft reacts on the
orbital speed of the Earth.

Now we know that the frequency from the stars reacts on the rotational speed
of the Earth (in agreemment with the Michelson-Gale experiment).

By the analogy the frequency should not react on the orbital speed (MM
experiment).

But I could not find the answer.
