I'm curious as to what folks are doing with PC's that require micro
second
accuracy for days or weeks or what have you.
Any examples?
Curious,
Steve
I hear of folks measuring time delay of off-air radio signals, where
millisecond accuracy is required. Data from multiple receivers in
multiple locations is compared. You need good accuracy for geolocating
weather satellite data - one second timing error can result in a 7 km
location error, so orbit prediction accuracy comes into that as well.
It's a similar requirement when pointing a narrow beamwidth antenna at a
distant satellite - note that they had to add a wider beamwidth antenna to
one of the ESA dishes trying to talk to the Phobos-Grunt probe recently.
Milliseconds suits me, though.
Cheers,
David
