Has anybody measured that? Is there a good URL on this? (predictions if not data) All I've found so far is a small NASA press release predicting 1.26 microseconds per day: http://www.nasa.gov/topics/earth/features/earth-20100301.html (and a zillion news sources repeating it) 1 microsecond/day is 1 part in 1E11. --------- >From a friend in radio astronomy (VLBI): They had a lot of the right instruments in the right place. Graph of position (3 meters!): http://ivsopar.obspm.fr/earth/tigo Description of the TIGO package: http://cddis.gsfc.nasa.gov/lw12/docs/Riepl_Tigo.pdf Letter from the director: http://www.expres-eu.org/Chile_06032010.html -- These are my opinions, not necessarily my employer's.
