The effect of gravity on clocks was tested to great precision by Vessot etal (1980, PRL, 45 2081) who launched a hydrogen maser straight up at 8.5 km/sec, and watched its frequency change as it coasted up to 10,000 km altitude and then fell back to Earth. ... To separate the Doppler shift from the gravitational effect, a transponder was used: the ground station transmitted pulses (blue) at a fixed rate, which were then echoed by the rocket (green) and detected on the ground. ...
