Sorry as a corection:
1: 30 km should be 3 km ( as you suggsted.
2: prof. Langley's experiments did not focus on radio occultations between two satellites partly through the Earth athmosphere of course, so only few measurements showed outliers (residuals) of 5 meters.

Well eeehh, as a second thought, you are right indeed.3km!!

so.... we have a problem to solve.
If my suggestion for the lightspeed extinction volume around the Earth see figure B. at:
bigbang-entanglement.blogspot.com/2006/0...dent-lightspeed.html

is not so tight as I suggested , then the problem is solved.
However, I think that a mountain summit ( as I suggested) will be too low to get enough data.

A baloon perhaps?

These signals are always far from Earth's surface. Doesn't that rule out your suggestion without need to concern ourselves with small atmospheric effects? -|Tom|-

What I did notice after studying the articles about POD (precise orbit detemination) of LEO satellites, is that there are problems to get good and enough radio occulations between LEOs and GPSs.
( esp. FORMOSAT-3)
Radio occulations are always "skimming" the Earth, which makes them in my view vulnerable for the effects which I am pointing at.

I am away from my computer for a week , so I must exuus myself for a while.

If My proposal for the Planetary (Earth) gravitational drag of the Lightspeed has a realistic base, as mentioned before, then all GPS signal readings taken by other satellites should account for such an effect.

Improvement of onboard GPS readings for precise orbit determination (POD) of Low Earth Orbiting (LEO) Satellites, like Formoasat-3, Camp, or Jason-1-/Topex-Poseidon satellites and ISS, are suggested to be possible, if these readings are taken into directions without any Earth-Solar orbital lightspeed influence.
A: for signals not directed into the Earth surface: Above 21 degrees above the horizontal-Earth line for Formosat-3 and Champ (both at about the same height) and Above 34 degrees for Jason-Topex satellites (cruising at higher levels) see figure B3.
OR;
B: if the orbital speed has no influence; GPS-readings taken perpendicular to the axis of orbital motion of the Earth round the Sun.
Outside these areas, the “Earth gravitational drag effect” should be incorporated into the GPS-reading calculations. This should be the case e.g. for so called LEO “GPS-occultations” skimming the Earth atmosphere.
