On a GPS satellite, the usual definition of the second applies. But in
order for the SIGNALS from GPS satellites to be received on earth at the

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.
