I dont have to debunk the service. I am not arguig against its existence.
Geostationary space satellites are debunked. Where you go from there is up to you.

Can you say something relevant.
You only have to explain how geostationary sats maintain a curved trajectory through space, while being pulled down by gravity, without falling around Earth curvature.

Orbital Velocity and Altitude
PREVNEXT
A rocket must accelerate to at least 25,039 mph (40,320 kph) to completely escape Earth's gravity and fly off into space (for more on escape velocity, visit this article at NASA).
Earth's escape velocity is much greater than what's required to place an Earth satellite in orbit. With satellites, the object is not to escape Earth's gravity, but to balance it. Orbital velocity is the velocity needed to achieve balance between gravity's pull on the satellite and the inertia of the satellite's motion -- the satellite's tendency to keep going. This is approximately 17,000 mph (27,359 kph) at an altitude of 150 miles (242 kilometers). Without gravity, the satellite's inertia would carry it off into space. Even with gravity, if the intended satellite goes too fast, it will eventually fly away. On the other hand, if the satellite goes too slowly, gravity will pull it back to Earth. At the correct orbital velocity, gravity exactly balances the satellite's inertia, pulling down toward Earth's center just enough to keep the path of the satellite curving like Earth's curved surface, rather than flying off in a straight line.
The orbital velocity of the satellite depends on its altitude above Earth. The nearer to Earth, the faster the required orbital velocity. At an altitude of 124 miles (200 kilometers), the required orbital velocity is a little more than 17,000 mph (about 27,400 kph). To maintain an orbit that is 22,223 miles (35,786 kilometers) above Earth, the satellite must orbit at a speed of about 7,000 mph (11,300 kph). That orbital speed and distance permit the satellite to make one revolution in 24 hours. Since Earth also rotates once in 24 hours, a satellite at 22,223 miles altitude stays in a fixed position relative to a point on Earth's surface. Because the satellite stays right over the same spot all the time, this kind of orbit is called "geostationary." Geostationary orbits are ideal for weather satellites and communications satellites.
How does it maintain it speed to maintain its trajectory through space if its in fact being pulled down by gravity.
How Satellites Stay in Orbit

So really, a satellites ability to maintain its orbit comes down to a balance between two factors: its velocity (or the speed at which it would travel in a straight line), and the gravitational pull between the satellite and the planet it orbits. The higher the orbit, the less velocity is required. The nearer the orbit, the faster it must move to ensure that it does not fall back to Earth.

A geostationary satellite has to be moving at a speed greater than the surface of the earth with a curved trajectory to stay geostationary above a specific spot on earth. Is that false.

Not this is not false. We have already been over this.
Are you now going to explain HOW geostationary sats maintain a curved trajectory through space, while being pulled down by gravity, without countering this by falling around Earth curvature like all satellites have to do.

You guys are hilarious. You keep posting the same dumb contradiction I debunked about 40 times now.

Geostationary orbit
en.m.wikipedia.org...
A geostationary orbit, often referred to as a geosynchronous equatorial orbit[1] (GEO), is a circular geosynchronous orbit 35,786 km (22,236 mi) above Earth's equator and following the direction of Earth's rotation. An object in such an orbit appears motionless, at a fixed position in the sky, to ground observers. Communications satellites and weather satellites are often placed in geostationary orbits, so that the satellite antennas (located on Earth) that communicate with them do not have to rotate to track them, but can be pointed permanently at the position in the sky where the satellites are located. Using this characteristic, ocean-color monitoring satellites with visible and near-infrared light sensors (e.g. GOCI) can also be operated in geostationary orbit in order to monitor sensitive changes of ocean environments.
The only thing dumb is that you cannot realize the earth’s rotation has nothing to do with earth’s gravity well.
Second: Why can you not get through your head a geostationary sat still obits the earth. It’s just at a speed that keeps it above a specific point and n earth.
From the earth’s surface. A geostationary satellite appears to be “fixed”. But that same satellite is traveling the “curve” of earth’s gravity well.
And you didn’t answer....
Not this is not false. We have already been over this.
