This takes your 7ps estimate to 700ps (which is more realistic).
There are LOTS of noise sources that have to be accounted for to get
precision measurements, including - ionospheric effects,
tropospheric effects, satellite orbit uncertainties, satellite clock
uncertainties, measuring instrument uncertainty (as Bob pointed out), and
even more.
