Speed of light in space is known thanks Roemer.s method. Now are radio
transmitters on the Mars and is possibility to use the Roemer's method
for radio waves. NASA know the results. Are thy pulished?

Of course, they're published. Widely. I would check Journal of
Geophysical Research or similar publications.

As a practical matter, precise measurements of the time of flight to/from
a spacecraft is used to figure out where the spacecraft is and its radial
velocity.

Typical range accuracy is on the order of a few meters, velocities good to
a few cm/s, for something at the orbit of Neptune or Uranus.

Precise doppler measurements are used for radio science experiments, e.g.
to determine the internal structure of a planet or moon by precisely
measuring the orbit of a satellite. A typical performance for such a
measurement is 1 part in 1E15 over 1000 seconds at 32 GHz or 8GHz.

Roemer's method is the one way measurement. See:
http://www.mathpages.com/home/kmath203/kmath203.htm

We know where Jovian is so the one way measurement is possible. With
spacecraft it is impossible.

not true. We do one way measurements from spacecraft all the time. A
high quality oscillator (aka USO)is used to generate a set of phase
coherent signals at different frequencies.

Look at PN ranging or Sequential Ranging.

Lately the one way is possible with the Mars. But independently for radio
waves and light. Mars has the satellite and radio transmitter.

As do Jupiter, Saturn, and outer planets
