Millimeter accurate GPS in smartphones and self driving cars would

I saw a different form of this article a month or so back, and for the
life of me I can't figure out how having a tiny atomic clock helps GPS
accuracy at all (nor how it would help w/ inertial reckoning, which was
a claim I saw in a different article on the same folks). Especially
since (AFAIK) the error budget of the GPS system in general far exceeds
"millimeter" accuracy, without post-processing all your data...
I'm also pretty sure numerous people here would object to the
characterization of atomic clocks as "room sized", in general. ;)
