Frequently Asked Questions (under construction!)
GPS Time Transfer
How do you know the GPS receivers in Gran Sasso and CERN are not introducing any systematic error?
Have you taken the antenna cable delay into account?
Does this system suffer from any kind of Sagnac effect, related to the rotation of the Earth?
What is the impact of the Ionosphere on the accuracy of the time transfer?
Fiber length calibration
Why haven't you used fiber reflectometry to measure fiber lengths?
These fibers are not length-compensated online. What is the length change throughout the year?
Beam Current Transformer cable calibration
You have calibrated using an LHC beam. How do those measurements apply to the CNGS beam?
