I assume satellites achieve geostationary orbit by using gravity effects from earth sun and moon and maybe a kick now and then from its own power?

Gravity effects from the earth only to a first order approximation. Satelites are essentially outside of the earth's atmosphere and close enough to the earth so that earth so that earth's gravity is dominant. A geostationary orbit is just an orbit in the plane of the equator with a period of 1 day. A circular orbit of 22,200 miles will work.

My question is how does it get up to that speed? Perhaps the delivery vehicle delivers that also, then vacuum does the rest plus onboard propulsion does the tweaking?

I think you've answered your own question here.

Yes the delivery vehicle gives it to the proper height and the required speed. Inertia then keeps the vehicle in the proper orbit with some tweaking required cause of the near vacuum. The orbit needs tweaking primarily because of gravity perturbations from moon and sun, maybe also some effect from the solar wind and the earth not being a perfect sphere. I think only a few tweaks per year are needed to keep satellites in a proper orbit.

To first order though, the moon's gravitational perturbations are cyclic and cancel out over monthly cycles. I just wanted to make it clear that there wasn't any special earth/moon/sun gravity thing that helped out. You can calculate the orbital distance and the required speed for a circular orbit from the mass of the earth alone.

I've often thought it would be great fun to watch a geocentrist try to explain geostationary satellites.

Absolutely.

I have to admit that today is the first time I'd ever given geocentrists much thought. My impression is that to be a geocentrist, you've already bought into a bunch of really silly physics that is way more fun to pick at than is your belief that the earth is stationary.

I'm sure a geocentrist could manage the task you describe here, and I'm also sure I'd be rolling on the floor laughing at the video.

Has anyone seen this? I cannot find it anywhere. Was it shown in any US theaters?

Re: Geocentrists I have known.
t would also be nice to keep the terminology straight. The earth does not rotate or revolve around the sun. The earth rotates/revolves about its axis. It orbits around the sun.

Minor nit pick here.

Rotate and revolve are not synonyms. Revolve is used by astronomers to mean orbit around. To revolve around the sun is to orbit the sun.
