Thirdly, as explained to him several times (in case you missed that), the stationary observer is IRRELEVANT for the case of the GPS. The starting point was the post containing the false claims pogono
made about his "solution" being "used by the GPS engineers". I pointed out over several pages that his claim was false, instead of admitting that, he moved the goal posts inserting the stationary observer and trying to solve a different problem. I merely pointed out that the solution to his new problem was a subset of the general solution I gave him.
Fourthly, if you are intent on solving yet another problem, the ratio of time dilation between a stationary observer and an observer on an elliptic orbit, my general solution produces the answer easily. But it is not the answer that pogono
came up with.
Fifthly, and most importantly, whatever the scenario, the time dilation is not additive and it makes no sense adding up proper time intervals with coordinate time intervals as pogono
has done repeatedly in this thread.
Sixthly, none of the above has anything to do with pogono's
ATM with the exception of his basic misunderstandings about GR, the Schwarzschild solution, observers, time dilation, GPS, etc. When one points out the various mistakes in his ATM, he simply manufactures a scenario that showcases his misconceptions about mainstream physics in general and relativity in specific.
