And circular motion needs a "constant downwards acceleration" of v²/R to maintain a circular orbit.

Great.
Shame gravity isn't providing that.
It's providing a constant downwards acceleration of 9.8 m/s2.

They seem the same to me!

They don't to me.

One is a squared velocity divided by a radius.

The other is not.

You are attempting to confuse centripetal acceleration with free fall.

Here's just one method of transmitting television signals over long distances that was in use as long ago as1957:

There are many more such methods that do not involves satellites.

It would, but acceleration BY inertia is counteracting it, and what we have is remaining longitudinal (forward) speed.
What other speed we have there?

Again, you label INERTIA as a force...

WTF is the matter with you?

Now you are deliberately hiding behind twisting.
Parroting same failed strategy from Papa Legba.

According to the Law of Action and Reaction, what is the reaction to gravitational force?

I did not twist anything.

You clearly wrote that inertia is causing acceleration.

Then satellite will not fall to the ground after all?
And on circular orbit tangential speed will not change?

No.

Inertia cannot cause acceleration.

Maybe we can dumb it down to something they can understand.

dutchy grabs a handful of feces from his ass, and throws it lightly, parallel to the ground. it flies a few yards before falling short of the enclosure fence.

legba throws his poop a little harder, just reaching the fence.

lackey, having the stronger arm, from constant masturbation, throws his shit much harder. It travels much further, splatting right on the face of his master, (they are all held captive by their yootoobe conspiracy video masters).

NASA, and their worldwide counterparts, have figured out how to throw complex electro-mechanical devices EXTREMELY fast... Fast enough that their trajectory matches that of the curvature of the planet, into the essentially frictionless environment of space, where it takes a very long time to hit the ground.

Now, you can watch your satellite TV, and with the number of broadcasts available, you can likely find video of the monkeyshit fights at the zoo.

You are contradicting yourself.
You are just stating that the proof you linked isn't valid.

And you add more things that require explanation:
"What goes up, must come down".

Where is "up"?
Where is "down"?
Why is "down" (or "up") where it is?
What will make things go "down"?

Gravitational force?

If that force acts upon satellites (action), what force acts as reaction?
What keeps up there all those and more satellites I already posted here?

Draw the free body diagram.

There is no other "force," acting on a satellite.

Why do you and Legba think that a free body diagram is appropriate to show how satellites stay in orbit when the horizontal velocity is a vital component that is omitted?

Or it the fact that the vital horizontal velocity component is not shown in free body diagrams the very reason that you are so obsessed with them?

Horizontal velocity...

I want to have you clearly on record for defining this term.

Am I to understand you mean an object traveling in a circular orbit relative to the surface of the earth?

As in this diagram?:

Satellite dishes are directional.  With the narrow band signals is my dish is off axis more than one degree I lose reception.  It's not possible for a high altitude balloon would need to be maintain it's position with the precision necessary for that kind of reception.

You are correct.  Troposcatter does bounce signals off the upper atmosphere but it's also dependent on atmospheric conditions (temperature, moisture, etc).

Those conditions greatly and again the precision necessary for small 18" dishes isn't there for consumer television.  Troposcatter dishes are a meter or more; much larger that direct broadcast satellite dishes.

Further, while troposcatter is capable of sending high bandwidth HD transmission, it can't handle transmitting several hundred such signals.  Even satellites can't do that.  In order to get my channels through DirecTV my dish receives signal from three different satellites with dozens of different transponders.

Not quite.  It would be more precise to refer to the "horizontal velocity" as a "tangential velocity", but most people seem to understand "horizontal velocity" in context of discussing orbits without making a fuss.
