Come misurare l’altezza di un satellite… guardando la televisione

This article deals with a rather simple method for measuring the height of telecommunication geostationary satellites. By observing the same telecast on two side by side displays, one of which is receiving the satellite image while the other is receiving from ground relay, some delay can be spotted between the arrival times of the two images, because of the different distance covered by electromagnetic waves. By using photographic and video recordings such delay can be measured and consequently the height of the satellite can be determined.
