The uBlox Max-7Q seems to be able to merge GPS and GLONASS for navigation, but

Hello,
Roughly, the temperature can be seen as a measure of the brownian motion (ie
shaking) of the atoms.
So if you keep the atoms at rest, it's equivalent to cooling them. One
definition of the absolute zero is that there is no motion of atoms.
