Considering that you pride yourself of having taught me all I know about the GPS, how come I know the answer to all these questions, and you do not? So the 'GR correction' is really a bit of a joke.

I know as well as you do that the free fall correction is built into the clocks before launch for good reason.

It would work quite well without it but would have to be corrected continually. That would amount to virtually the same thing as building in an offset before launch.

Which is that each individual clock must be in synch with the GPS time, and that the situation that the clocks are in synch with each other and NOT in synch with the GPS time is a bltant impossibiliy? They dont HAVE TO BE in synch with the ground clocks but it certainly helps. So what? In other words, the only difference between my and your positions on this is the choice of words. You use the term "GR correction". I correctly refer to it as the "free fall" correction. Does that mean that we agree on the following statements: Without 4.46*10^-10 correction which the designers used GR to calculate, the GPS would not work. The GPS thus prove that the correction predicted by GR is correct. Funny boy. The system is fine tuned when in orbit. That is a very simple software procedure. There is NO GR correction. A free fall correction is required due to the fact that the clocks are not perfect. Try using a pendulum clock, Paul. On second thoughts, try using the period of Jupiter as the unit of time for both orbiting and ground clocks. Do you think the period of Jupiter changed when the GPS system was launched? An even better idea might be to use the GPS satellite orbit as the unit of time. You can name the correction whatever you like, Henry. That cannot change the fact: It was calculated by GR. Not so, it includes a fictitious velocity component. We all know tat clocks do not change physical rates when a force is applied for a period and then removed. Which direction do you think their rates would change, Paul?
