> How precise GNSS satellites orbits are between 20000km and 30000km. 20kkm is 0.06671s of c, 30kkm is 0.10007s, 5km is 0.000016678. So a very precise, that's

So a very precise, that's why they have an atomic clock on board instead of cheap quartz one. > if the two differ by 50,000 metres, you know something is going wrong Like what your imprecise methods give you a very rough estimate where is the terminal and your legitimate customers in the nearby areas (not even doing anything for or against) are saying thanks for their shut off terminals. https://upload.wikimedia.org/wikipedia/commons/b/b4/Comparison_satellite_navigation_orbits.svg https://upload.wikimedia.org/wikipedia/commons/b/b4/Comparis... https://www.omnicalculator.com/physics/light-year https://www.omnicalculator.com/physics/light-year
