Sigh... sorry but Einstein had nothing to do with putting satellites in space.<p>If anything you&#x27;re talking about the working of the GPS system and even in that case, the effects of gravity are below the error of the device. (clock drifts dealt with via regular ground synch)<p>The only appreciable effect is the ephemeris calculation which uses relativistic doppler calculations. Unfortunately the difference between normal doppler and relativistic doppler is minuscule at these speeds and are also within error ranges... So ultimately even the GPS argument doesn&#x27;t hold water..<p>So... like, go with Jonas Salk who gave away the fortune that was the Polio vaccine. That&#x27;s a real hero.
