That has been done very accurately.

None of them uses the two way time transfer technology.
And none of them has been conducted outside the atmosphere.
Generally short path lengths and abnormal propagation delays limit
the efficacy of such experiments.

Kindly name a single experiment either conducted or proposed
so far, which has attempted to measure the velocity of the
barycenter of our solar system in the Universal Reference Frame.
