Default Geostationary satellites

Geostationary satellites hang above a longitude meridian and orbit the Earth at the same rate as the planet turns in the direction of daily rotation. It stands to reason that the orbit of the satellite is basically an extension of the Lat/Long system into space so the Equatorial speed at sea level will be 1037.5 miles per hour and once 24901 mile rotation in 24.

The central reference of the satellite is the Earth in front of it so although it will not pick up the surface rotation of the North South poles parallel to the orbital plane, it may catch the edge of the Antarctic Continent move annually.

It should have alerted people to the fact that we see the same thing when the Sun is a central reference as both rotations combine to create the variations in the natural noon cycle.
