When a clock of GPS ground base will inndicate 2024-08-31 17:00:00.00000000 - what will be indication of a clock in GPS satellite? Take the simultaneity of the base. It's not another gedanken, it's an unique real situation, soon it will happen and will never happen again. My prediction is: it will be 2024-08-31 17:00:00.00000000, with the precision of an acceptable error. For any functional GPS satellite. What is the prediction of your moronic physics?
