On a GPS satellite, the usual definition of the second applies. But in

geoid (mean sea level).

 
monseneor, you misundrestand the entire procedure -it's not about the
signal propagation, but the difference in the gravity gradient. The
signals transmission are implied, but only after that.

I see people are not replying in this science newsgroup. I feel depressed.
