"You are getting off track."

Which track? You always jump on another track then running out of arguments.

"We are discussing heliocentrism and geocentrism, not whether relativity is true or not."

To do this, I have to know if you accept relativity. I'm still not sure about that topic.


"And GPS is a geocentric system, not a barycentric system."

From your link:
"The coordinates produced by GPS are geocentric coordinates based on the center of the earth with X, Y and Z components."
You have do distinguish between the system GPS is working with and the coordinates it produces. GPS uses geocentric and barycentric systems. On which system do you think a satellites orbit is calculated for flying around a planet with a moon?

From the abstract you posted:
"Whether one uses a solar-system barycentric frame or a geocentric frame when including the general theory of relativity in orbit determinations for near-Earth satellites, the results should be equivalent to some limiting accuracy."
And some keywords:
"CENTER OF GRAVITY, EARTH ORBITS, GEOCENTRIC COORDINATES, ORBITAL POSITION ESTIMATION, RELATIVISTIC THEORY, SATELLITE ORBITS, EARTH ROTATION, [...]"

"And apparently, were GPS a barycentric system, corrections would be required:"

Where did you read that? "conventional barycentric equations" is in physics a system there you neglect relativistic effects. A geocentric system is also a barycentric system as you may know. For some folks a very special one.


"Doesn't look like GPS is any support for heliocentrism."

Read my posts and you'll see I only claimed GPS is a hint for relativity.
Try to light another straw-man.

A straight question to you:
Do you think the earth is rotating?

You are the one posting strawmen.

The subject has always been geocentrism vs heliocentrism.
