BTW... There is a recent, well informed post on sci.physics.research
that discusses some of the causes of errors in the GPS.

I realise you would take the opposite view but it left me
no confidence that the 7us/day correction can be attributed
to predicted motional effects wrt earth. Even if a science
quality geostationary oscillator was avalible as we discussed
it might take a Ouji board to pull the signal out of the
system's phase noise.


Where is Tom Roberts with his error bars when ya need him? ;-)

The Sagnac interferometer at Wettzell
http://www.wettzell.i***.de/LKREISEL/G/LaserGyros.html
is now integrated with GPS so might be a good source of
data to settle that sort of issue without need for a dedicated
SV or heaven-forbid you and I have to take your 100Khz crystal
calibrator up there ourselves and show 'em how it's done. ;-)
