I guess that is why some GPS antenna cables is temperature-stabilized as well
as the cement-pidestal for the GPS antenna as it stands on solid rock. The same
place have controlled environment for the cesiums and hydrogens, together with
UPS and disel-engine that kicks in for longer runs.

Or I could be wrong... :)
